  • The Case for Glycine Heap Leaching

    Project Target 2Gold ore with nuisance copper. Gold ores with elevated or nuisance copper levels are difficult to process by conventional cyanide heap leaching, as the copper causes high cyanide consumption. As well as the direct cyanide cost, this increases the cost of detoxifying effluent solutions.
