钾盐浮选药剂研究进展

Research Status of Potassium Salts Flotation Regents

为使钾盐浮选科技工作者更好地认识钾盐浮选药剂的研发现状和发展趋势，介绍了国内外钾盐浮选常用的各类捕收剂、调整剂和起泡剂。重点介绍了十八烷基伯胺、十二烷基磺酸钠等捕收剂在钾盐浮选中的研究和应用现状。对国外粗粒钾盐浮选药剂研究作了重点介绍，如松香酸甲酯与C8-C18脂肪酸混合物、氢化松香醇一煤油溶液与脂肪胺混合物、脂肪胺和氧丙烯醇的组合用药等都可用于粗粒钾盐的浮选。指出捕收剂分子烷基碳链结构多样化、多官能团化、若干种药剂组合用药等是今后钾盐浮选药剂研究和发展的方向，强调粗粒钾盐浮选药剂的研究对未来钾盐浮选工业发展具有重要意义。

Various collectors,regulators and froths that were widely used in potassium salts flotation at home and abroad were introduced,in order to make potassium salts technology, workers better understand the current situation and development trend of potassium salts flotation. The research and application status of collectors, such as C18 alkyl primary amine and sodium dodecyl sulfate, used for potassium salts flotation were emphasized. And flotation reagents of coarse potassium salts at home and aboard were introduced prominently, such as the mixture of abietate and Cs ~ Cls carbamate aliphatic acid, mixture of hydrogen- ated abieticalcohol-kerosene and aliphatic amine, and mixture of aliphatic amine and alkoxy-propylalcohol. It was pointed out that research and development direction about potassium flotation regents in the future would include the diversification and muhi-functionalization of alkyl chain structure in a collector molecule, and several regents combination etc. It is emphasized that the research on flotation regents of coarse potassium salts plays a significant rule in development of potassium flotation in- dustry in future.
