Nickel processing - Extraction and refining | Britannica

Sulfide mining, which is sometimes referred to as hard-rock mining, is the process of extracting trace amounts of copper, nickel and other metals from sulfide ores. When sulfide ore comes into contact with water or oxygen, a chemical reaction occurs and produces sulfuric acid, which is the same as battery acid.
