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 can then be precipitated with an alkali, as sodium ...

Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the orebearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it's usually necessary to sink vertical mine shafts to access coal which is deposited in layers or 'seams ...

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and costeffective when the uranium ore is located near the surface (, within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
