Optimal design and planning of heap leaching process
2014年2月1日· 1 Introduction Heap leaching is a hydrometallurgical process that is widely used in the mining industry, in which lowgrade metals, such as copper, gold, silver and uranium, are extracted; the process also has new applications in the treatment of nonmetallic minerals, such as saltpeter (Valencia et al, 2008), and soil remediationThe Phase 2 heap leach facility will consist of an enlarged heap leach pad, an additional event pond, additional larger solution handling pumps and an additional CIC plant The new mill facility will consist of a twostage crushing facility, conveyors, ball mill circuit, gravity concentration, leach and CIL tanks, thickeners, filters and a reagent handling areaEquinox Gold Announces Positive Feasibility Study for Castle
