摘　　要：在硫化矿物浮选分离中有机抑制剂的研究是一个重要的发展方向。有机抑制剂具有种类多，来源广，抑制能力强等优点。采用德兴铜矿石研究了新型有机抑制剂ＣＴＰ在铜硫矿物浮选分离中的抑制效果。试验结果表明，在ｐＨ９～１０，ＣＴＰ用量为６０ｇ／ｔ时，可有效实现铜硫矿物浮选分离，精矿铜品位达到２４％，作业回收率为９７％。Study on organic depressant in sulfide flotation separation is one of important trends in recent years due to its large quantity, abundant resources and high depressing, etc. The depressing actions of a new organic depressant CTP in the separation of copper and sulfur have been studied with ores of Dexin Copper Mine. The results show that the separation of copper and sulfur was carried out succesfully in the dosage of CTP 60g/t at pH 9 ～ 9.5. Copper concentrate with copper grade over 24% is obtained, and the recovery of copper is above 97% in the separation process. \ \
