: Adding reagents to force metals out of the solution as solid compounds. Industrial Applications
: Employs specialized resins to adsorb specific ions from the solution.
: Uses sodium hydroxide, essential for the Bayer process to produce alumina.
: Critical for recovering copper, gold, nickel, and uranium from low-grade ores.
: Uses electric current to deposit metal onto a cathode.
The hydrometallurgical process typically follows a three-stage sequence:
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.
