摘　　要：为了提高钼精矿的质量,抑制其中的铜和铅,在铅、铜的传统无机抑制剂基础上,组合使用一些有机药剂进行试验,最后筛选出巯基乙酸钠20 g/t、磷诺克斯30 g/t、TMT1000g/t的抑制剂组合,得到了钼精矿中铜品位为0.25%,铅品位为0.82%的浮选指标。To improve the quality of molybdenum concentrate as well as suppress the copper and lead content, on the basis of the traditional inorganic inhibitors of lead and copper, some organic reagents were used to test. Finally, the combination of depressants was selected including sodium thioglycolate of 20 g/t, phosphorus Locks of 30 g/t, and TMT of 1000 g/t. And the flota- tion indexes were obtained with copper grade of 0.25% and lead grade of 0.82% in molybdenum concentrate.
