【摘要】 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药剂的代用品更多还原

【Abstract】 The flotation separation of the gold bearing sulfide ore from the Gaowang Gold Mine with a new thionocarbamate ZL4020 as collector is investigated in this paper. Compared with butyl xanthate, the use of ZL4020 as collector can not only obtain similar concentrate grade, but also increase recoveries of copper and gold by 2%, respectively and reduce reagent cost by 25%. The reagent can be used as substitute for Z 200 due to its better performance and low price.更多还原
