Applications Extraction of iron from its oxides:In a Blast furnace Oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and coke are fed from its top.Hot air is blown from the bottom of the furnace and coke is burnt to give temperature upto about 2200K in the lower portion itself. The burning of coke therefore supplies most of the heat required in the process and will be oxidised to CO. The CO and heat moves to upper part of the furnace. In upper part, the temperature is lower and the iron oxides (Fe2O3 and Fe3O4) coming from the top are reduced in steps to FeO. Limestone is also decomposed to CaO which removes silicate impurity of the ore as slag. The slag is in molten state and separates out from iron.Equation here for lime stone. Thus, the reduction reactions taking place in the lower temperature range and in the higher temperature rangedepend on the points ofcorresponding intersections in the ΔrG minus verses T plots. These reactions can be given as follows:At 500 -- 800 K lower temperature range in the blast furnace. 3 Fe2O3 + CO gives 2 Fe3O4 + CO2 equation 11. Fe3O4 + 4 CO gives 3Fe + 4 CO2 equation 12. Fe2O3 + CO gives 2FeO + CO2 equation 13. At 900 -- 1500 K higher temperature range in the blastfurnace:C + CO2 gives 2 CO equation 14. FeO + CO gives Fe + CO2 equation 15. The iron obtained from Blast furnace contains about 4% carbon and manyimpurities in smaller amount (e.g., S, P, Si, Mn).

Our topic for today is Electrolytic Refining of Metals. Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis. Let us learn how copper is refined electrolytically. Take acidified copper sulphate solution as the electrolyte. Take a thick rod of impure copper and a thin rod of pure copper. Make impure copper as the anode and pure copper as the cathode. When current is passed through the solution, the CuSO4 electrolyte splits into copper ions and sulphate ions. The copper ions from the electrolyte get attracted towards the cathode. The copper ions gain 2 electrons from the cathode and deposit as pure copper atoms on the thin copper rod. At the same time, the copper atoms from the anode lose 2 electrons, convert into copper ions and dissolve in the electrolytic solution. In this way, indirectly, copper atoms from the anode deposit on the cathode. Hence, size of anode decreases and size of cathode increases. In this way, all the pure copper from the anode deposits on the cathode. The impurities in the impure copper rod settle down as anode mud at the bottom of the container.

Iron ore washing is the process to reduce contaminants and thereby increasing the iron content of the raw iron ore, known as increasing the Fe value. Our technology has been effectively used for processing: Blue Dust DRI Lumps Sinter feed Iron Ore Mines The processing of low grade iron ore fines includes effective removal of alumina, silica, silt, clay etc. from the feed material. This increases energy efficiency of kilns and avoids frequent shut downs to allow contaminating material to be removed. This has the effect of increasing the FE value of the iron ore, leading to a high efficiency steel production process. Our iron ore washing system has been deployed by majority of leading steel producers in India. This shows our phenomenal success in delivering highest efficiency of steel production through our iron ore washing systems.

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today. This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment. The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.

Iridium is a transitional metal, which is located in the middle of the periodic table, below rhodium. If we take a look at the prevalence of all elements in the earth's crust, Iridium holds the last place, that is a billion atoms of all that there is and only one atom of iridium. This metal is 40 times rarer than gold. In much higher concentrations iridium is found in meteorites and also in the depths of the Earth, in magma. Interestingly enough, in the layers of rock sediments, though more precisely in the formation of clay, that is aged about 66 million years there were found high concentrations of iridium and this can indicate the collision of Earth with a huge meteorite in the past, which in theory was the cause of the death of the dinosaurs. In it’s appearance iridium is a shiny metal that does not oxidize in air. This metal has almost the highest density of all metals, just 0.12% lower than that of osmium - the most dense metal. In this tiny tiny metal droplet, which is of the size of a match head, we have 1 gram of iridium. To help you understand how high is the density of iridium, I will show other metals with the same mass for comparison. Lead, copper, gallium, zinc, magnesium, and the lightest metal - lithium. The volumes of the first and last metal differ by about 30 times, although their mass is the same. Iridium is also a very hard metal that is firmer than the solid steel in 1.5 (one and a half) times. Iridium, in addition to its rarity is even the most stable metal that does not oxidize in air up to 2000 degrees, and is not soluble in either acid or aqua regia. Iridium can only react with the fluorine at temperatures of about 600 degrees. Unfortunately, due to the low activity of iridium, I cannot conduct any chemical experiments or have quality reactions with it. The only thing that I can do is make a fine powder of iridium and set it on fire in the air, but as you can see, in this case iridium dust is burning quite slowly and also requires dispersing it in the air. For the first time on youtube, you can observe a burning iridium. Also, due to the low activity of iridium, the metal does not tarnish in air, even when heated to above 1,000 degrees. The only thing that the drop of iridium got covered with is a partially evaporated ceramic layer, the one that the forceps are made from. Iridium compounds are can be either brown or yellow, such as the complex of Vasca, which is used as a catalyst in organic chemistry. By the way, Iridium is the only element that can give away 9 electrons and form compounds with +9 (plus nine) oxidation state. Iridium now finds many uses in science and technology. In most cases, we will probably find iridium in spark plugs for vehicles, due to the high stability of iridium to oxidation under the influence of electric discharge. Pure iridium is used for making crucibles for growing single crystals, foil for making non-amalgam cathodes, as well as as a part of the highly resistant to corrosion alloys. The first standard of mass of one kilogram was created in 1889 using an alloy composition of 90% platinum and 10% iridium and is called the International Prototype Kilogram, it is still kept in the Paris Chamber of Weights and Measures. Now you know more about one more of the elements, if you would like the scientific series of the elements to continue, please subscribe to my channel and also throw in some likes if you can!

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. There are five types of crushers; Jaw crusher, Gyratory crusher, Cone crusher, Impact crusher and Mineral sizers. A gyratory crusher is consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. Material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces. A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.

www.le.ac.uk https://www2.le.ac.uk/departments/geology/research/vtmrg/tease A shift from fossil fuels to low-CO2 technologies will lead to greater consumption of certain essential raw materials. Tellurium (Te) and selenium (Se) are 'E-tech' elements essential in photovoltaic (PV) solar panels. They are rare and mined only in small quantities; their location within the Earth is poorly known; recovering them is technically and economically challenging; and their recovery and recycling has significant environmental impacts. Yet demand is expected to surge and PV film production will consume most Se mined and outstrip Te supply by 2020. Presently, these elements are available only as by-products of Cu and Ni refining and their recovery from these ores is decreasing, leading to a supply risk that could hamper the roll-out of PV. Meeting future demand requires new approaches, including a change from by-production to targeted processing of Se and Te-rich ores. Our research aims to tackle the security of supply by understanding the processes that govern how and where these elements are concentrated in the Earth's crust; and by enabling their recovery with minimal environmental and economic cost. This will involve 20 industrial partners from explorers, producers, processors, end-users and academia, contributing over £0.5M. Focussed objectives across 6 environments will target key knowledge gaps: The magmatic environment: Develop methods for accurately measuring Se and Te in minerals and rocks - they typically occur in very low concentrations and research is hampered by the lack of reliable data. Experimentally determine how Te and Se distribute between sulfide liquids and magmas - needed to predict where they occur - and ground-truth these data using well-understood magmatic systems. Assess the recognised, but poorly understood, role of "alkaline" magmas in hydrothermal Te mineralisation. The hydrothermal environment: Measure preferences of Te and Se for different minerals to predict mineral hosts and design ore process strategies. Model water-rock reaction in "alkaline" magma-related hydrothermal systems to test whether the known association is controlled by water chemistry. The critical zone environment: Determine the chemical forms and distributions of Te and Se in the weathering environment to understand solubility, mobility and bioavailability. This in turn controls the geochemical halo for exploration and provides a natural analogue for microbiological extraction. The sedimentary environment: Identify the geological and microbiological controls on the occurrence, mobility and concentration of Se and Te in coal - a possible major repository of Se. Identify the geological and microbiological mechanisms of Se and Te concentration in oxidised and reduced sediments - and evaluate these mechanisms as potential industrial separation processes. Microbiological processing: Identify efficient Se- and Te-precipitating micro-organisms and optimise conditions for recovery from solution. Assess the potential to bio-recover Se and Te from ores and leachates and design a bioreactor. Ionic liquid processing: Assess the ability of ionic solvents to dissolve Se and Te ore minerals as a recovery method. Optimise ionic liquid processing and give a pilot-plant demonstration. This is the first holistic study of the Te and Se cycle through the Earth's crust, integrated with groundbreaking oreprocessing research. Our results will be used by industry to: efficiently explore for new Te and Se deposits; adapt processing techniques to recover Te and Se from existing deposits; use new low-energy, low-environmental impact recovery technologies. Our results will be used by national agencies to improve estimates of future Te and Se supplies to end-users, who will benefit from increased confidence in security of supply, and to international government for planning future energy strategies. The public will benefit through unhindered development of sustainable environmental technologies to support a low-CO2 society.

Copper is low down in the reactivity series. It is not very reactive. The more reactive a metal is, the more difficult it is to extract from its ore. Reactivity series. What is an ore? Ores are rocks that contain varying amounts of minerals from which metals can be extracted. Still need to separate the metal from other elements in the compound. Extracting copper. Why can copper be found as copper in the ground (native)? It is not very reactive. There are also ores that contain copper. Heating with carbon. Task. 1. Mix together 3 spatulas of copper carbonate and 1 spatula of carbon 2. Add the mixture to a boiling-tube. 3. Heat gently at first and then more strongly. 4. Record all observations. 5. When will you know that copper has been extracted? Heating with carbon. Why was carbon used? What type of reaction is this an example of? Suggest what products were formed. Answers. Carbon is more reactive than copper and so removes the oxygen. Removing oxygen is called reduction. The carbon gains oxygen and this is called oxidation. copper carbonate - copper + carbon oxide dioxide copper oxide + carbon - copper + carbon dioxide Copper mining. For every 2kg of copper 1000kg of copper ore needs to be extracted. What impact will this have on the local environment?

In every part of the world, and in every important or trivial aspect of our lives -- every time we eat or drink, write or paint, wash, cook, travel, or simply sit in the hearth of our home -- we avail ourselves of some derivative of metallic and nonmetallic mineral ores. From our faded jeans to our toothpaste; our televisions and mobile phones, or even a seemingly-trivial product like cat litter; from solar panels to cosmetics -- all of these products, use processed minerals. And the list is endless. Even if we are largely unaware of it, minerals exist in and affect our daily lives, and we co-exist intricately with them.

Mineral Jigs: https://www.savonaequipment.com/en/equipment/gold-concentrating-refining/gold-concentrating-tables-e41438 Mineral jigs are a type of mining equipment, also referred to as gravity concentrators or jig concentrators, that are used in operations to separate different ore materials based on their densities. Usually they will process material that is a similar size after the ore has passed through a crusher or over a screening plant. Although there are many variants that will take place in a mineral jig, certain principles remain constant. Material is first fed into the jig bed, usually made with a screen, then propulsing columns thrust water upward which suspend particles in the water because they have been exposed to gravitational energy. Frequencies normally range in between 125-350 strokes/minute. In between the pulses material that is heavier will be trapped in the bed filled with steel shot (small round steel media) and settle in the bottom of the jig and the concentration is removed separately for further processing with an example being over a gold concentrating table or if the grade is high enough in a smelting furnace. If a jig concentrator is being used for minerals that are lower in density, coal being one, the gravitational energy has a reverse effect because material around coal is heavier and the coal will float towards the top. #savonaequipment #miningequipment #goldrecovery #mining ♦️Grinding MIlls: https://www.savonaequipment.com/en/equipment/mills-grinding-mills-e41552 ♦️Gold Concentrating & Refining: https://www.savonaequipment.com/en/equipment/gold-concentrating-refining-e41436 ♦️Steel Media: https://www.savonaequipment.com/en/equipment/mills-grinding-mills/grinding-media-e64499

Some of the ore samples I've collected. Several mines open to claim. The first sample I show in this video is from the Green Mountain Pit, which is the same claim that has the hidden adit. I need to do a video just of the ore from that 20 acres since it's so majorly different from the pit to the adit, and within different points of the adit as well. Amazing geology really. I couldn't have been more wrong on accessibility, four wheel drive only. Of course it's now claimed.

Hidden deep below the green hills in Jharkhand is India's rich uranium resource. At Narwapahar in Jadugoda town, mining operations are highly mechanised, there are no rusty lifts. Here, one can drive into mines through the kilometres of underground highways that leads one to the uranium ore. The ore lies between 70 to 1,000 metres below the ground. To extract the ore, almost 300 to 400 tonnes of rock is blasted, drilled and brought to the surface.

I am pleased to take this opportunity, it is my great delight to participate and present technical paper in MEAI’s National Seminar “Road Map To-wards Sustainable Mining” organized by MEAI with support of DGMS, DMGK and MSAK. It is an honor for me to evolution of knowledge at your kind consideration. This Technical paper contents the brief meaning of sustainable mining, Management information system, Human Resource Development Training scope in sustainable mining & Responsibilities. Miners Job stress impact on sustainable mining and Strategies for miners working pressure. It is my privilege to being a part of the event. Thank you sir, Yours truly, Shivayogi G Abbigeri, Meaning of Sustainable Mining Sustainable mining refers to the growth of our natural resources (minerals) and energy resources, onshore and offshore, in a way that make best (maximum) use of the economic and social benefits while minimizing the environmental impacts of mining. It integrates environmental, economic, safety and community aspects in all stages of a project. The term sustainable development means different things to different people. But, in essence, it is concerned with meeting the needs of people today without compromising the ability of future generations to meet their own needs. Sustainable mining concerned with meeting the needs of people today without compromising the gift of future generations to meet their own needs. According to Kirkey, "Green mining is defined as technologies, best practices and mine processes that are implemented as a means to reduce the environmental impacts associated with the extraction and processing of metals and minerals. Examples include the reduction of greenhouse gases, selective mining approaches to reduce the ecological footprint, and reduction in chemical use. He also says that this technology "helps reduce operating costs for the mining industry and improve its competitiveness". Kirkey says, "Reducing the environmental impact of mining and related activities continues to be one of the most significant and important challenges for the sector. The industry’s public image is strongly together to its environmental performance and recognizes that it must improve to ensure it remains responsible, competitive and productive." The demand for mineral resources increases, so the pressure on the environment. Land quality deficiency, decrease of water resources and corrupt of groundwater, air pollution from dust and other pollutants. These processes need to be addressed in the initial stages, in order to ensure that best practices are preventative measure in the arrangement of the industry. Mining can become environmentally sustainable by developing and join together practices that reduce the environmental impact of mining operations. India’s domestic, automotive sector and power sector demands are motivating to production growth in several minerals like steel, aluminum, zinc and fuel minerals. Infrastructure buildup is seeing strong growth, not only on housing, but also on projects like roads, rail and airport luxury buildings, and other necessities. Karnataka, Chhattisgarh, Odisha, Madhya Pradesh, Andhra Pradesh, Jharkhand, Goa, Maharashtra, Tamil Nadu, Rajasthan and Kerala are the major Indian producers of iron ore. Karnataka is the largest producer nearly one-fourth of the total produced in India. contact for seminars, Conferences, Workshop Training Program & Counsellings.

Animation of atomic bombs: https://www.youtube.com/channel/UCocSPp2haPIl0_edFrDimPw Hi everyone! I guess you have figured that this video is going to be about such a metal as uranium. However, let me make give a small warning in order to calm you down. I think now we have settled everything and can move on to considering properties of the most dangerous metal on earth - uranium. Uranium belongs to the actinides series in the periodic table that is to radioactive elements and its atomic number is 92. Uranium is 40 times more abundant in earth’s crust than silver. It forms in abundance upon rapid neutron capture inside spinning supernovas. That is why uranium was discovered quite early, in Germany in 18-th century. Its discoverer, Martin Heinrich Klaproth, named it after a newly discovered planet of the solar system, after Uranus. In nature uranium is often found in such minerals as uraninite and autunite. This metal often has several oxidation states in those minerals. Thanks to the beautiful yellow colour of such minerals, glass blowers added them to glass. As a result minerals would give such glass a beautiful greenish colour. It’s a pity that back then craftsmen didn’t not about the toxicity of uranium compounds. Nevertheless, pure metallic uranium can be obtained from uranium ore via reduction by calcium which looks very ordinary. Since mostly uranium naturally occurs in the form of uranium-238 isotope with a half-life of about 4.468 billion years, in 99, 23% of cases to be precise. Depleted uranium is most frequently used for chemical researches, that is uranium-238, in order to reduce scientists’ exposure to its radiation. Also there are only two radioactive metals that occur naturally. Those are uranium and thorium. It’s so because of their extremely long half-lives. Pure uranium obtained from its ore looks quite dark as its surface oxidizes pretty fast because of the high chemical activeness of this metal. That is why it is often stored in argon and also all experiments with uranium are conducted in argon medium. Usually a piece of pure metallic uranium-238 is ripped to such small shreds on a lathe in a laboratory. It is noteworthy that these shreds in the test tube already emit beta and gamma radiation.

The federal Bureau of Land Management on Wednesday renewed mineral rights leases for a proposed Twin Metals copper-nickel mine in northeastern Minnesota, a project that environmentalists fear would spoil the pristine Boundary Waters Canoe Area. Department of Interior Assistant Secretary for Land and Mineral Management Joe Balash renewed the leases following a 41-day public review and comment period. "Mining on public lands balances conservation strategies and policies with the need to produce minerals that add value to the lives of all Americans by providing raw materials used in the manufacture of medical aids, automobiles, smartphones and computers, and household appliances," Balash said in a statement. "Mining strategic metals in the United States is beneficial to national security, national and local economies, and job creation." The leases cover land in the Superior National Forest 9 miles (14 kilometers) southeast of Ely that encompasses vast reserves of copper, nickel and precious metals. According to Twin Metals Minnesota, the renewed leases add new conditions, including higher annual royalty payments, project milestones and additional environmental requirements. Twin Metals Minnesota CEO Kelly Osborne calls the lease renewal "a critical step" for the company to present its proposal for an underground mine. "It's very good news for us and for the communities in northeastern Minnesota who look forward to the hundreds of jobs and major economic development this mine will bring," Osborne said in a statement. Twin Metals, which is owned by the Chilean mining company Antofagasta, said it plans to submit its mine proposal to state and federal agencies in the coming months for environmental and scientific review. Environmental groups are fighting the project, fearing mining would spoil the nearby Boundary Waters Canoe Area, the country's most-visited wilderness. Nine area businesses who contend the project would hurt their business are suing in federal court to block the leases. No hearing is scheduled yet, but Jeremy Drucker of the Campaign to Save the Boundary Waters expects a hearing in early fall. Tom Landwehr , the campaign's executive director and former commissioner of the Minnesota Department of Natural Resources, called the announcement "a continuation of the Trump Administration's assault on the Boundary Waters Wilderness," and said the review was "wholly insufficient to determine the impact of sulfide-copper mining on land immediately adjacent to the Boundary Waters." The copper, nickel and precious metals under northeastern Minnesota are bound up in sulfide ores that can release sulfuric acid and heavy metals when exposed to air and water. In September, the Trump administration said it would allow copper mining near the Boundary Waters, reversing a decision made in the final days of the Obama administration. In late 2016, the Obama administration withdrew about 234,000 acres of the Rainy River watershed near Ely from elig

Daily Mining Activity. Little Help Out For Friend. Mining is the extraction of valuable minerals or other geological materials from the earth usually from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

Day 2 - Bryan Lovell Meeting 2019 - The role of geological science in the decarbonisation of power production, heat, transport and industry Speaker: Lluis Fontboté Since 1990, Lluis Fontboté has been a full professor at the University of Geneva, Switzerland, where he leads a research group on ore deposits that is active worldwide. His main area of expertise is epithermal polymetallic deposits linked to porphyry systems, iron oxide copper gold deposits, and MVT zinc-lead deposits. In collaboration with his students and coworkers, Lluís has also published work focusing on VHMS and orogenic gold deposits, on acid mining drainage and on the future of global mineral resources. He has worked in exploration for several commodities, mainly in the Andes. Abstract Recycling is important and essential, but is not enough to meet the strong growth in demand, in particular from developing countries. Rapid evolution of technologies and society will eventually reduce our need for mineral raw materials, but at the same time, these new technologies are creating new needs for metals, such as many of the 60 elements that make up every smart phone. Climate-friendly technologies will add pressure to the growing demand on mineral raw materials. According to several reports, meeting a 2°C global temperature warming scenario would imply important added annual consummation of several metals including lithium, indium, neodymium, copper, cobalt, silver, zinc, lead, molybdenum, iron, and aluminum. In contrast to articles announcing that deposits of mineral raw materials will be exhausted within a few decades, geological evidence indicates that the resources of most mineral commodities are sufficient to supply countless future generation as long as there is a major effort in exploration (e.g. Arndt et al., 2017). Confusion between the terms mineral resources and reserves is the main reason of the widespread misconception of a rapid exhaustion of mineral resources. Large regions of the Earth are underexplored and it must be taken in account that the vast majority of mined deposits have been discovered at the surface or in the uppermost 300 meters of the crust. Geological evidence shows that deposits are also present at greater depths. Mining technology is ready for mining at depths of 3000 m and more. In addition, price increases can render economically viable deposits with grades too low to be mined today. However, there is potential for temporary future shortages of certain mineral raw materials. Society needs to be aware that (1) recycling is not enough to meet the increasing demand of metals; (2) that, therefore, search and exploitation of new ore deposits is necessary; and (3) that technical solutions exist to minimize the impacts associated to mining activities. This is a complex endeavour and requires technical improvement but also of a communication effort from the involved stakeholders. Developments of electromagnetic and seismic and 3D imagery as well as the use of "big data" and machine learning approaches and identification of large crustal structures offer new opportunities. The big challenge there is to form geologists able to cope with the generated data wealth. This includes solid knowledge in Earth science basics including mineralogy, petrology, structural geology, geochemistry, and fieldwork skills, analytical and synthesis capacity, and at the same time, ability to collaborate with specialists in other fields.
