Hydrometallurgy: Principles And Applications -

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 first stage where target metals are dissolved into a liquid solution using chemical solvents (lixiviants). and recycled materials. Unlike pyrometallurgy

: Commonly uses sulfuric acid for copper and uranium. which relies on high-temperature smelting
