Hydrometallurgy is the use of aqueous solutions to extract metals from ores. Hydrometallurgical processes include leaching, precipitation, and electrolysis. Leaching involves the dissolution of a metal from an ore using a solvent. Precipitation involves the formation of a solid metal compound from a solution. Electrolysis involves the use of an electric current to deposit a metal from a solution.
