新型黄金浮选剂的合成及浮选性能研究

Synthesis and Floating Function of New Gold Flotation Reagents

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 % 。

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.
