    The process design of gold leaching and carbon-in-pulp

    concentration of gold in the aqueous phase is typically between 0.001 and 0.02 ppm with a value of 0.01–0.005 ppm regarded as a practically achievable value for most well-designed and operated plants. This represents a gold recovery of 90–99% depending on the tenor of the feed solution. These high recoveries are achieved because the carbon is
