摘要: 采用江西理工大学研制的DT系列抑制剂对江西某铜银多金属矿进行了低碱度铜硫分离浮选试验研究。试验结果表明,以DT系列中的DT-2#作为铜硫分离浮选时黄铁矿的抑制剂,可在pH=8的低碱度条件下获得铜精矿、硫精矿品位分别为22.49%和33.07%,回收率分别为88.76%和62.25%的良好指标,而且银在铜精矿中的品位和回收率分别达到1 391.6 g/t和71.59%。

Abstract: The experiments on flotation separation of Cu-Fe sulfide at low basicity for a Cu-Ag multi-metal ores in Jiangxi province is carried out by using the DT series depressor produced by Jiangxi University of Science and Technology.The results showed that in flotation separation of Cu-Fe sulfide, with the DT-2# as the depressor of pyrite at low basicity of pH 8, copper and sulfur concentrates grading at 22.49% and 33.07% with an 88.76% and 62.25% recovery are achieved respectively.Meanwhile, the silver grade and recovery reach 1 391.6 g/t and 71.59% in the copper concentrate.
