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 ...
