: Adding reagents to force metals out of the solution as solid compounds. Industrial 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.
: Uses organic solvents to selectively bind target metal ions. Hydrometallurgy: Principles and Applications
: Methods vary from Heap Leaching (spraying ore heaps) to Autoclave Leaching (high-pressure vessels).
: Used to extract precious metals like gold and silver from discarded circuit boards. : Adding reagents to force metals out of
: Employs specialized resins to adsorb specific ions from the solution.
: Dissolved metals are separated from impurities. : Uses organic solvents to selectively bind target
: Commonly uses sulfuric acid for copper and uranium.
