Cyanidation of a pyrrhotitebearing gold ore
gold and is an unlikely reaction to significantly consume dissolved oxygen and cyanide (Dunn et al, 1995) Pyrrhotite is in much higher concentration than gold in a gold ore The oxygen requirement by the pulp will depend on the concentration of pyrrhotite in the ore Pyrrhotite is in much higher concentration than gold in a gold ore The oxygen requirement by the pulp will depend on the concentration of pyrrhotite in the ore and the degree of oxidation of its surface A study on hexagonal pyrrhotite indicated a very low solubility in aerated cyanide solutions (Linge, 1995)Cyanidation of a pyrrhotitebearing gold ore 911 cyanidation of a pyrrhotitebearing gold ore as a function of lead nitrate addition The mass balance calculation on cyanide showed that the cyanide consumed by the formation of thiocyanate was reduced by more than 55% (from 35% to 15%) The cyanide consumed by the formation of(PDF) Cyanidation of a pyrrhotitebearing gold ore
