Abstract. The effects of silver sulfide Ag 2 S on the bioleaching of chalcopyrite and pyrite were investigated in this paper. It has been shown that Ag 2 S enhanced the yields of bioleaching of chalcopyrite but inhibited the bio-oxidation of pyrite. The addition of Ag 2 S selectively increased the copper dissolution from the chalcopyrite-containing ores in shake flasks with a recovery of 85 ...
