Hydrometallurgy

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. The complement to hydrometallurgy is pyrometallurgy, which is usually older technology. Hydrometallurgy is typically divided into three general areas:
