2021-8-11  dissociable (WAD) cyanide in leach tails could rise over 50mg/L in cyanidation plants, which is the limit of cyanide code (Logsdon et al., 1999; Mudder and Botz, 2004). This fact might require to include a cyanide destruction operation in gold/copper plants in order to treat leach tails, increasing the operational and capital costs. 3.

2011-5-1  In a CIP plant, leaching is complete before the first adsorption tank, and gold is then recovered from the leached pulp in a series of (typically) 4–10 dedicated carbon adsorption tanks. In a CIL plant, the carbon is added directly into the leach tanks, with the claimed advantage of lowering capital costs by eliminating the CIP adsorption tanks.

Strategies for the optimisation of gold processing plants

Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that 100% recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.
