Future Of The Hydrometallurgical Processes In Copper Ore

US5223024A Hydrometallurgical copper

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of
