【摘要】 根据软硬酸碱规则 ,设计并合成了六类含硫有机浮选剂 ,实验了这六类浮选剂从浮选厂尾矿中提取黄金的浮选性能 ,得到了从尾矿中富集黄金的最佳捕收剂—次甲基二乙基二硫代氨基甲酸酯。它对浮选尾矿中金的提取率 >90 % ,为工业开发应用及我国资源充分利用提供了一条可行性方案更多还原

【Abstract】 Six types of gold flotation reagents were studied through design and synthesis.A systematic test of 6 type chemical compounds was performed to collect gold from mine tailing.By the test of floating,it was found that the best collection reagent of gold-ethylene bis(dimetyldithiocarbamato).It can extract gold from mines tailing,and the extraction rate of gold is more than 90%.This method can be widely applied in industry,and provide an approach for sufficiently utilizing mineral resources in China.更多还原
