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, e.g. as sodium ...

The Properties and Applications of Platinum - ThoughtCo

Although studied by a number of English, French and Spanish chemists in the mid-18th century, Francois Chabaneau was the first to produce a pure sample of platinum metal in 1783. In 1801, Englishman William Wollaston discovered a method for effectively extracting the metal from ore, which is very similar to the process used today.
