Sulfuric acid is used to leach uranium from certain ore types, often together with an oxidant such as ferric iron. Such leaching occurs either in situ, in heaps or in agitated uranium recovery from solution (typically by solvent extraction) the residual, acidic solution bleed requires neutralization and treatment to remove the dissolved metals.

Uranium ores are generally classified as acidic, alkaline, or phosphate rock based. In all cases, the ore is milled and classified prior to leaching. Since the final milling is done in a ball or rod mill as a slurry, it is necessary to concentrate the milled ore slurry in a preleach thickener prior to the leaching process in order to reduce ...
