Background
Acid leaching (a cid leaching) refers to a mineral leaching process that uses an aqueous solution of a mineral acid as a leaching agent. It is one of the most commonly used leaching methods in chemical ore dressing. Sulfuric acid, hydrochloric acid, nitric acid, sulfurous acid, hydrofluoric acid, aqua regia and the like can be used as the leaching agent, wherein the most widely used is sulfuric acid. The dilute sulfuric acid is weak oxidizing acid, can be used for treating mineral raw materials containing a large amount of reducing components (such as organic matters, sulfides, ferrous oxide and the like), is low in cost and easy to obtain, the problem of corrosion resistance of equipment is solved easily, the sulfuric acid solution has a high boiling point, and a high leaching temperature can be adopted at normal pressure. Hot concentrated sulfuric acid is a strong oxidant, which can convert most of the sulfide minerals into corresponding sulfates. The reaction capability of the hydrochloric acid is stronger than that of the sulfuric acid, and the oxysalt minerals which cannot be leached by the sulfuric acid can be leached out, but the hydrochloric acid has higher price, is volatile, has poorer labor conditions, and has higher corrosion resistance requirement than the sulfuric acid.
