摘要
二甲基二硫代氨基甲酸丙烯腈酯是一种新型高效的硫化矿捕收剂,对复杂和高寒地带的硫化矿具有捕收能力强和选择性好的特点。通过正交试验得出最佳工艺条件:丙烯腈∶二硫化碳∶二甲胺(mol)=1∶1.1∶1.05,反应温度控制在(20±2)℃,反应时间6 h在此条件下,可合成含量大于75%,产率在80%以上的产品。在用量为30 g/t戊基黄药和80 g/t二甲基二硫代氨基甲酸丙烯腈酯时,与用300 g/t戊基黄药比较,铜粗选金属回收率提高3.57个百分点,提高铜粗选精矿品位0.86个百分点。
Acylonitrile ester N,N-dimethy dithiocarbamate is a new type of high efficient collector on sulfide ores,which has very strong collecting and selecting ability on sulfide mineral in complex and extremely cold district.Orthogonal test is made to determine the best process conditions： the mixture ratio of Acrylonitrile,Carbon disulfide and Dimethylamine（mol）1∶1.1∶1.05,reaction temperature at 20 ±2℃,reaction time 6 h,the component 75%,the rate of product 80%.Metal copper recovery rate can be improved by 3.62% and copper rough concentrate grade increased by 0.93% with Sodium petylxanthate dosage of 30 g/t and Acylonitrile ester N,N-dimethy dithiocarbamate 80 g/t,comparing with Sodium petylxanthate dosage of 300 g/t.
