This is a method of metal or metal compound extraction from an ore through pre-treatments that involve the use of a leaching agent, separation of impurities and precipitation. It is used in the extraction of uranium, gold, zinc, silver and copper from low-grade ores. This process has been improved by the development of processes like solvent extraction and ion exchange.
More so, it is a branch of extractive metallurgy that uses aqueous solutions to recover metals from ores, concentrates, and recycled materials. It’s commonly used for metals such as copper, gold, nickel, and uranium, particularly in cases where traditional smelting methods aren’t feasible due to low metal concentrations or environmental concerns(What Is Hydrometallurgy?, n.d.).
