Interdisciplinary field involving processes that are driven by microbes - bio. mainly take place in aqueous environment - hydro deals with metal production and treatment of metal containing materials and solutions - metallurgyBeginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SXEW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20 of all copper produced is produced by this is process.
