: Critical for recovering copper, gold, nickel, and uranium from low-grade ores.
: Used to extract precious metals like gold and silver from discarded circuit boards.
: Essential for reclaiming lithium, cobalt, and nickel from spent lithium-ion batteries to support a circular economy . 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.
: Dissolved metals are separated from impurities. : Critical for recovering copper, gold, nickel, and
: Uses electric current to deposit metal onto a cathode.
: The final stage where the metal is returned to a solid, purified form. : Uses electric current to deposit metal onto a cathode
: Employs specialized resins to adsorb specific ions from the solution.
