  • COMPARISON OF CYANIDE AND THIOSULPHATE

    Before leaching the gold ore must be crushed and grinded into small particles usually particle size varies between 30 and 180 μm. Free milling ores are ready for leaching after crushing and grinding whereas refractory ores need pretreatment. It is important to pretreat a refractory ore before leaching to achieve better gold extraction.

  • COMPARISON OF CYANIDE AND THIOSULPHATE LEACHING

    In agitation leaching cyanide consumption typically varies for free milling ores from about 0.25 to 0.75 kg/t and if there are cyanide consuming minerals then cyanide consumption varies from about 1 to 2 kg/t. In heap leaching cyanide consumption is lower than in agitation leaching.

  • Application Note Cyanide Leach ProcesspH

    process. Heap leaching involves crushing the ore to <3/4" (<19mm) diameter chunks and piling on a puncture-proof liner. The liquid cyanide solution is poured over the heap and allowed to percolate down through the ore. The gold containing solution (pregnant leach) is collected from the liner into a leach pond and sent off to carbon adsorption.
