    Processing Heap Leachable Gold Ore by Cyanidation Oxide ore (low grades) will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH. Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction. After the leach cell is harvested, the irrigation system shall be

  • Silver Gold Cyanide Leaching of Copper Ore

    Much work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2, Cu(CN)3=, and Cu(CN)4=, although Cu(CN)3= is considered the most probable of these. According to leach scientists, the complex having an empirical formula KCu(CN)2, is not a solvent for gold and silver.

    Copper and Cyanide Recovery in Cyanidation Effluents

    High pH values and high freecyanide concentrations stabilize copper in solution resulting in lower levels of copper. Increment of copper in the barren solution poses serious metallurgical problems in the cyanidation circuit and it is necessary to include a process to strip the copper, prior to the gold and silver leaching step.

Over recent years a cyanide recycling process known as SART (sulfidisation, acidification, recycle, and thickening) has gained attention as a method to remediate the increased costs and potential environmental impact caused by using cyanidation to process copper bearing gold ores.
