(57) This invention describes a hydrometallurgical process for extracting and recovering valuable metals contained within metalliferous minerals including ores, concentrates and other materials and generation of useful by-products including sulfur, calcium, oxygen, carbon and hydrogen, wherein the process comprises the use of a hydrogen generator, such as an water electrolyser, hydrocarbon pyrolyser or reformer to produce hydrogen, and optionally carbon and oxygen integrated into a single circuit that converts the CO2 and SO2 pollutants that would be emitted by the conventional pyrometallurgical process into the useful by-products.
