Iron Ore About 98% of iron goes toward steel production. 500 dry metric tons NYMEX Lead Batteries, protective shielding, ammunition and industrial sheets. 25 metric tons COMEX Molybdenum Molybdenum is primarily an alloying agent with steel. The metal is also used in the production of petroleum,...
Australiahas several resources it could leverage, including renewable energy and natural gas, to become a leader in hydrogen production. It additionally has vast iron ore deposits that could be used to produce HBI for export or green steel products or semi-finished products. Swedenalready has...
The other side of the coin of commodity prices is global demand. In the case of the commodities, you have to consider which economies are more dependent on raw materials, as well as those countries who produce them. A good example of this is China, a populous country that is rapidly beco...
Much like a boiling pot of water, the salts evenly and thoroughly heat the steel. Photo courtesy Don Fogg Knives A salt bath used by Don Fogg When the blade is removed from the forge or salt bath, it must be immediately placed into the quench tank. The oil in the quench tank causes...
data can be used to answer the question: how long did it take in 1970 and does today in 2020 to produce as much metal as has been produced in the entire history before 1970, i.e. how long are the doubling periods (See model inAppendix). Table2shows that the doubling periods became ...
The petrified wood is much harder and resistant to weathering than the mud rocks and ash deposits of the Chinle. Instead of eroding away, the wood accumulated on the ground surface as the surrounding mud rocks and ash layers were eroded away. That is why areas of the Park are covered with...
Adding cryolite allows the electrolysis to occur at a much lower temperature. The electrolyte is placed in an iron vat lined with graphite. The vat serves as the cathode. Carbon anodes are immersed in the electrolyte. Electrical current is passed through the molten material. At the cathode, ...
last year for a whopping $3.5 billion because Newcrest’s assets are very much mature. Ironically Newmont spun-off Newcrest almost 30 years ago and the buyback of mature assets appears a desperate move, even if the bid for shares was at a modest premium. Does size matter? This deal is ...
This is because with the two-stroke cycle, there are twice as many combustion events (which produce the power) per revolution. It turns out that the diesel two-stroke engine is really much more elegant and efficient than the two-stroke gasoline engine. See How Diesel Two-Stroke Engines Work...
When Forrest returned, fully recovered, to Australia, he declared Fortescue, a miner of iron ore, was going all-in on green hydrogen. He believes the market could be worth as much as $12tn by 2050. “The journey to replace fossil fuels with green energy has been moving at glacial speed...
