摘　　要：介绍了铜钼分离抑制剂的种类 ,阐述了巯基乙酸作为铜钼分离有机抑制剂的研究发展及应用现状。在江西德兴铜矿进行的选钼工业试验表明 ,巯基乙酸是一种优良的有机抑制剂 ,能完全取代硫化钠 ,同时能有效地降低选矿药剂成本。最后展望了有机抑制巯基乙酸在实际应用中尚待解决的一些问题。The varieties of copper sulphide depressants were introduced. The development and present situation of thioglycolic acid as an organic depressant for Cu-Mo separation were presented. The industrial experiment, in Dexing Copper Mine in 2000, showed that thioglycolic acid was a quality organic depressant, and could substitute Na 2S completely as the depressant. Finally, some problems to be solved in its application were put forward.
