Certain gold concentrates are treated by the biological oxidation-cyanidation process which obtains high gold grade,about 5 g/t,in tailings.To more effectively recover gold from cyanide tailings,study on the surface property and floatability of gold-bearing pyrite is carried out.The results show that in the biological oxidation-cyanidation tailings,pyrite floatability is evidently poorer than in the gold concentrate;the slurry potential has great influence on the pyrite floatability in cyanidation tailings:the flotation recovery rate decreases with the potential;increased collector use is beneficial in improving pyrite flotation recovery rate.The research result can provide reference for the recovery of gold from biological oxidation-cyanidation tailings.
