SA-3对铜铋硫化矿分选分离的作用及机理研究

Sorting effects and mechanism of SA-3 on copper bismuth sulphide

摘要: 利用单矿物试验研究了SA-3对辉铋矿和黄铜矿浮选行为的影响，研究表明：SA-3对辉铋矿的抑制能力极弱；当SA-3用量为50 mg/L时，黄铜矿受到强烈抑制.红外光谱分析表明：SA-3是一种包含-SH、-OH、-COOH的多官能团抑制剂，文中对SA-3在黄铜矿表面的作用进行了分析.

Abstract: This paper studies the effect of chalcopyrite and bismuthinite's floatation with SA-3. The results show that the inhibitory ability of SA-3 to bismuthinite is very weak. Chalcopyrite received strong inhibition when the dosage of SA-3 is 50 mg/L. Infrared spectrum analysis demonstrates SA-3 is a kind of functional organic inhibitors. -SH, -OH and -COOH are SA-3' functional groups.
