Dec 22, 2018Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.
Uranium is the basic fuel for a nuclear power reactor uranium is a very heavy metal able to release abundant concentrated energy. Uranium occurs naturally in the Earth's crust and is mildly radioactive. Depleted uranium is a by product from uranium enrichment.
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining

An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore mineral or metal, as
