| 摘 要： | 以对碳化硅表面有选择性的脂肪酸作为捕收剂,采用泡沫浮选分离方法来分离回收硅片线锯砂浆中的和碳化硅粉。研究了捕收剂浓度、起泡剂浓度、浮选溶液的温度及pH值对分离效果的影响。当浮选溶液中捕收浓度为0.315mol/L,起泡剂浓度为0.18mol/L,温度为70℃,pH值为4.5时,分离效果最佳:浮起产物中碳化粉质量分数为99.3%,沉淀产物中硅粉质量分数为95.9%。

| Abstract: | Using fatty acids as a selective collector of the silicon carbide surface, the effective separation was achieved by froth floatation separation technology. The effects of collector concentration, frother concentration, temperature and pH value of floatation solution on the separation result were investigated. The obtained best separation result shows that the mass fraction of the SiC powder in the float is up to 99.3%, and the mass fraction of the Si powders in the deposit is 95.9% under the collector conce... |
