摘　　要：研究了在低碱条件下,乳酸、单宁酸、水杨酸、焦性没食子酸等有机抑制剂对黄铜矿、黄铁矿可浮性的影响。试验表明:这几种有机抑制剂都能一定程度地抑制黄铁矿,在铜硫浮选分离过程中,添加少量的焦性没食子酸或单宁能成功实现铜硫分离。The effects of several organic depressants, for example lactic acid, tannic acid, sahcyhc acid, pyrogallic acid on flotability of chalcopyrite and pyrite have been studied under the conditions of low alkali. It is concluded that these organic depressants can inhibit pyrite to a certain degree, particularly in separation of copper and sulfur by flotation. In flotation, addition of a small amount of pyrogallic acid not only can separate copper and sulfur successfully, but also help comprehensively recover associated valuable components such as gold, silver, molybdenum and cobalt.
