摘　　要：浮选柱的开发和应用已有120多年的历史,主要应用在煤和硫化矿的浮选,在磷矿选矿领域的应用相对较少。从浮选柱的发展历程、柱体结构、发泡器类型的介绍出发,围绕浮选柱类型和浮选柱浮选工艺详细阐述了浮选柱在磷矿选矿领域的应用,实践证明,浮选柱处理细粒级磷矿效果良好,具有较好的应用前景。Flotation column has been developed and employed for more than 120 years,which is mainly amenable to flotation of coal and sulfide ores,with little use found in phosphate ores dressing.Starting from the development history,structure,bubbler style of flotation column,the presentation on the application of flotation column in phosphate ore dressing was focused on the flotation technologies with types of flotation columns.From the practices,it is proved that the encouraging flotation results obtained from processing fine fractions of phosphate ores using flotation column indicates its promising application.
