  • designing of a vat leaching plant for gold processing

    information on cyanide leaching of gold leach plants. Since the 1890's, cyanide has been used to recover gold from gold bearing ores. Much thought and design goes into the making of a heap leach, to derive the best, most zinc precipitation process and the other is the adsorption of the gold onto activated carbon.


    modelling involves conducting batch gold leaching and carbon adsorption tests with representative samples of ore or concentrate contacting commercially available activated carbon or plant carbon. The rate of leaching is determined in a traditional bottle roll experiment. Timed samples of
