摘　　要：我国有大量难处理的微细粒矿产资源,选择性絮凝技术是提高微细粒矿物回收的有效途径之一。首先分析了微细粒矿物的性质及其难浮选的原因,其次阐述了选择性絮凝的相关理论研究进展,最后对目前常见的选择性高分子絮凝剂进行分类,并对絮凝剂和选择性絮凝分选工艺在微细粒矿物分选中的研究和应用现状进行了分析和总结,认为絮凝剂选择性较弱、成本偏高、会产生环境影响、絮凝设备缺乏等是目前存在的主要问题,指出开发选择性强的新型絮凝剂、絮凝设备和絮凝工艺是未来的发展趋势。China has a large number of refractory fine−grained mineral resources,and selective flocculation technology is one of the effective ways to improve the recovery of fine−grained minerals.This article first analyzes the properties of fine mineral particles and the reasons why they are difficult to float.Secondly,it elaborates on the theoretical research progress of selective flocculation.Finally,it classifies the common selective polymeric flocculants currently available and analyzes and summarizes the research and application status of flocculants and selective flocculation separation processes in fine mineral particles.The main issues identified are the weak selectivity of the flocculants,high cost,environmental impact,and lack of flocculation equipment.The article points out that the development of new,highly selective flocculants,flocculation equipment,and flocculation processes is the future trend.
