N—苯基-2-硫醇基苯骈咪唑(简称咪唑)是用于不经预先硫化而浮选氧化的炭酸铜和硅酸铜的一种捕收剂。东川矿务局中心试验所在辽宁省冶金研究所帮助下,1966年以来对我局的氧化铜矿进行了小型浮选试验,一般可提高回收率3%左右,主要是提 N-phenyl-2-mercaptobenzimidazole (referred to as imidazole) is a collector for the flotation of oxidized copper and copper silicate without prior vulcanization. With the help of the Liaoning Provincial Institute of Metallurgy, Dongchuan Mining Bureau Central Test Station conducted a small flotation test on the copper oxide ores of our bureau since 1966, generally increasing the recovery rate by about 3%
