feb 03, 2021 the newly added coal gangue produced in the past three years is about 650 million tons, and only about is used for underground filling. this sounds to me as though they want to miners to put the leftover material after mining back into the mines, perhaps so it wont blow around all over and so that the depleted mines wont subside
other sources are russia, zimbabwe, the united states, and canada. the global nickel reserve base, occurring as magmatic sulfides and laterites, is estimated at million tonnes of contained metal shared between australia, new caledonia, brazil, russia, cuba, indonesia, south africa, the philippines, and china.
gravity separation or concentration gravity separation is the separation of minerals of different specific gravity by their relative movement in response to gravity and one or more other forces, usually the resistance to motion by viscous fluid such as water or air. water-based or air-based processes are used to concentrate minerals and coal, based upon differences in particle specific gravity.
the benchmark is 0.877 mt of cmwh for standard coal plants over 300 MW and 0.979 mt of cmwh for standard coal plants below 300 mw. for less common plants that burn coal gangue or coal water slurry, the benchmark is 1.146 mt of cmwh, while
