2013-7-11  Leaching is a hydrometallurgical method that permits the beneficiation of gold ores from deposits which would else be uneconomic because of their fine gold distribution or their relatively low gold grades. Leaching processes, however, are not limited to such ores. The chlorination process, which is obsolete by now, used chlorine gas that was
