Effect of pH on Au Recovery in the Presence of % Stibnite (After Hedley Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that recovery is once again achieved at pH 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.

01/11/2015 · The liberated gold is then leached by different methods, mainly by cyanidation [11âˆ'14]. Cyanide consumers include iron, copper, zinc, cobalt and nickel ions, etc. [5].
