How to Control Pollution in Mining Industry?

Mine Water Pollution: The mining Industry has to discharge millions of gallons of water every day to the adjacent water courses thereby may cause water pollution problems in and around the mining areas. Mine water discharge also forms the main source of various water supplies particularly potable in the thickly populated coal fields.

The ore is transported on belt conveyors from the ore storage to the grinding circuit. Water is added during grinding and the ore is ground in two stages, with autogenous grinding in the primary stage and pebble mill grinding in the second. Autogenous grinding means that the ore grinds itself without the addition of external grinding media.
