摘要
随着易选铜铅锌硫化矿资源的日益消耗,大量难选氧化矿资源的开发利用日益被重视。硫化浮选法是氧化矿富集回收的主要方法,但硫化效果直接影响浮选指标。分析了孔雀石、白铅矿和菱锌矿的表面特性及难选原因,阐述了这三种典型氧化矿的表面硫化机理、氧化矿的强化硫化方法和研究进展,目的是为铜铅锌氧化矿表面强化硫化及高效浮选分离提供参考。
With the decrease of easily beneficiated copper-lead-zinc sulfide ore resources,the development and utilization of a large number of refractory oxidized ore resources becomes important.Sulfide flotation is the main method for enrichment and recovery of oxidation ore,but the effect of sulfide directly affects the flotation index.In this paper,the surface characteristics and refractory reasons of malachite,cerussite and smithsonite are analyzed.The surface sulfidization mechanism,enhanced sulfidization method and research progress of these three typical oxide ores are discussed.The purpose is to provide some reference for enhanced vulcanization and efficient flotation separation of copper,lead and zinc oxide ores.
