Ammonia leaching has been used in the past to recover copper from copper oxide minerals associated with carbonate gangue material. Descriptions of a former ammonia leaching operation have been given by Duggan and Eddy. Leaching of copper minerals by cyanide solutions has been proposed by Lower and Booth, but as yet has not been used in practice.

Bioleaching is used today in commercial operations to process ores of copper, nickel, cobalt, zinc and uranium, whereas, biooxidation is used in gold processing and coal desulfurization. Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid.

The use of sulfuric acid in an acid leaching process is a conventional method for recovery of copper, but in some cases it is necessary to use other reactants such as ammonia. Ammonia has been known as an effective leaching agent in hydrometallurgical procedures, although it has been less studied than the chemical agents used in leaching.
