THE EFFECT OF PROCESS VARIABLES ON CYANIDE AND

factorial design investigations found that SART is largely affected by sulfide to copper molar ratio and cyanide to copper molar ratio. The economic analysis identified the optimum operating conditions for the SART process as a sulfide to copper molar ratio of around 0.56, a pH of 4, and minimised cyanide to copper molar ratio.

These e ects mainly interfere with the gold cyanide reaction and the carbon adsorption. Most of the copper minerals react rapidly with cyanide, forming multiple cyanide complexes.
