Effect of Pretreatment of Sulfide Refractory Concentrate

pyrite were the main minerals present on the concentrate. The best results for gold extraction were obtained with oxy gen pressure of 80 psi, 10% (w/w) sodium hypochlorite, temperature of 80C, at pH = 13, and a constant stirring speed of 600 rpm. These conditions allowed an approximated 60% of gold and 90% of silver extractions in 1 hr.
