对新型硫氨酯ＺＬ４０２０浮选分离高旺金矿的伴生金铜矿石进行了研究。工业试验结果表明，与丁基黄药相比，在精矿品位相近的情况下，ＺＬ４０２０浮选的铜、金回收率分别可提高２％，药剂费用降低约２５％。与Ｚ－２００药剂相比，ＺＬ４０２０的性能略优，但价格便宜，可作为Ｚ－２００药剂的代用品
A new type of thiocarbamate ZL4020 flotation separation Gaowang gold associated gold and copper ore were studied. Industrial test results show that compared with butyl xanthate, recovery of copper and gold of ZL4020 can be increased by 2% and the cost of medicament can be reduced by 25% when the concentrate grade is similar. Compared with Z-200, ZL4020 slightly better performance, but the price is cheap, can be used as Z-200 Pharmacy substitutes
