Lime products play a key role in the mining and extraction of non-ferrous metals, including aluminum, copper, gold, nickel, cobalt, uranium, titanium and lithium. Lime is also important for the pyrometallurgical refining and smelting of several non-ferrous metals. In addition, lime products are used in effluent and tailings treatment, and in settling, dewatering, filtration,
