| 摘 要： | 研究了几种不同的表面活性剂对锌精矿有机溶剂在浆萃取过程中锌浸出率的影响 ,并对表面活性剂的用量对锌精矿在有机溶剂中的行为进行了探讨 ,测定了经表面活性剂处理后矿粉在水溶液中的粘度以及浸出溶液表面张力变化情况 ,结果表明加入 0 .0 5～ 0 .2 g/L表面活性剂十二烷基磺酸钠改变了矿粉在水溶液中的润湿性 ,降低了浸出溶液的表面张力 ,有效地提高了锌精矿浸出率

| Abstract: | The effects of different surface active agents on the solvent extraction in leaching sphalerite were discussed.It is found that sodium dedecylsulfonate is an effective surface active agent in the improvement of zinc recovery of sphalerite.Through surface tension measurements and the viscocity analysis of modified sphalerite by different surfactants,it is concluded that sodium dodecylsulfonate in the range of 0.05～0.2g/L can improve the wettability of sphalerite,decrease the surface tension of leaching solvent ,prevent the aggregation of ore particles,and offer very high zinc extraction. |
