Heap Leaching of Copper Ores
Jan 01, 2019Heap leaching is practised in three main types of applications: sulphuric acid leaching of copper oxide ores, cyanide leaching of gold ores as well as the oxidative acid leaching of secondary copper sulphide ores, usually with the assistance of certain microorganisms and, more recently, in the presence of chlorides (CaCl2, sea water).

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description.
