锡石浮选药剂研究进展

Research Development of Cassiterite Flotation Reagents

锡是现代工业不可或缺的关键战略金属,我国的锡矿资源十分丰富,但随着优质锡矿的消耗,锡矿资源贫、细、杂的特点越来越突出,微细颗粒、伴生组分复杂也是回收锡矿资源面临的技术难题。浮选作为回收微细粒锡石的主要方法,浮选药剂的选择至关重要。概述了常见的脂肪酸类捕收剂、胂酸类捕收剂、膦酸类捕收剂、烷基磺化琥珀酸捕收剂和羟肟酸类捕收剂的特点及作用机理,重点介绍了新型羟肟酸捕收剂在锡石浮选中的应用成果,以及捕收剂与活化剂、抑制剂在锡石浮选过程的组合使用,为锡石新药剂研发提供参考。

Tin is an indispensable key strategic metal in modern industry.In China,Tin ore resources are abundant,however,with the depletion of high-quality tin ore,the characteristics of tin ore resources being poor,fine,and mixed are becoming increasingly prominent.The presence of fine particles and complex components has become a significant technical challenge in the recovery of tin ore resources.Flotation,as the primary method for recovering fine cassiterite,demands a crucial selection of flotation reagents.In this paper,the characteristics and mechanisms of common fatty acid collectors,arsenic acid collectors,phosphate collectors,alkyl sulfosuccinic acid collectors,and hydroxamic acid collectors were summarized.The application results of novel hydroxamic acid collectors in cassiterite flotation and the combination of collectors,activators,and inhibitors in cassiterite flotation were emphatically introduced,which provide a reference for the development of new reagents in cassiterite flotation.
