Sulfuric acid is one of the most critical by products used to make hundreds of compounds needed by almost every industry. The largest amount of sulfuric acid is used to make phosphoric acid, which in turn is used to make the phosphate fertilizers, calcium dihydrogenphosphate and the ammonium phosphates.

KCM’s new Nchanga smelter includes a 1,850 ton per day sulphuric acid plant, which produces sulphuric acid primarily for KCM’s Tailings Leach Plant (TLP). Surplus acid is sold to customers within and outside Zambia.
