Underground mining (hard rock) Wikipedia

There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody.

The MiningMilling Process The Piedmont Environmental

MiningMillingTailingsThere are three forms of uranium mining: open pit mining, deep mining; and in situ leaching. Open pit mining creates large holes dug into the ground to remove the ore and waste rock which impedes ore extraction. This method is frequently used when the desirable ore is close to the surface. The mining operation planned in Pittsylvania County in the 1980s would have been a 110-acre hole, 850 feet deep. Deep mining creates shafts dug into the ground to reach ore at d

Uranium Mining Overview World Nuclear Association

Mill chemistry. The crushed and ground ore, or the underground ore in the case of ISL mining, is leached with sulfuric acid: UO 3 + 2H + ====> UO 2 2+ + H 2 O UO 2 2+ + 3SO 4 2-====> UO 2 (SO 4) 3 4-. The UO 2 is oxidised to UO 3.. With some ores, carbonate leaching is used to form a soluble uranyl tricarbonate ion: UO 2 (CO 3) 3 4-.This can then be precipitated with an alkali,
