: The first stage where target metals are dissolved into a liquid solution using chemical solvents (lixiviants).

: Critical for recovering copper, gold, nickel, and uranium from low-grade ores. Hydrometallurgy: Principles and Applications

: Commonly uses sulfuric acid for copper and uranium.

Hydrometallurgy is a specialized branch of extractive metallurgy that uses aqueous solutions to recover metals from ores, concentrates, and recycled materials. Unlike pyrometallurgy, which relies on high-temperature smelting, hydrometallurgy operates at relatively lower temperatures and is increasingly valued for its ability to process low-grade or complex ores more sustainably.

The hydrometallurgical process typically follows a three-stage sequence: : Commonly uses sulfuric acid for copper and uranium

: Uses electric current to deposit metal onto a cathode.
