Abstract

This paper deals with the effect of the addition of lead nitrate and ultra-fine grinding on the cyanidation of an antimonial refractory gold and silver ore. The results indicated that the recovery of gold was enhanced by 10%, but, silver extraction did not improve with adding lead nitrate or increasing its concentration. Fine grinding (e.g. down to-5 mu m) did not produce the desired effect on the extraction of Au and Ag.
