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

: Uses sodium hydroxide, essential for the Bayer process to produce alumina. Hydrometallurgy: Principles and Applications

: Methods vary from Heap Leaching (spraying ore heaps) to Autoclave Leaching (high-pressure vessels). : The first stage where target metals are

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. and recycled materials.
