简介了近年来国内外对浮选柱的研究及应用情况,并重点推介国外几个大型选矿厂应用浮选柱提高铜精矿品位的生产实践。笔者认为目前铜钼混合精矿粗精矿再磨再选段采用浮选柱+常规浮选机结合的原则流程已趋成熟;工业生产中浮选柱设备的大型化、多样化表明了推广应用的可靠性。 The research and application of flotation column at home and abroad in recent years are briefly introduced. The production practices of flotation column to improve the grade of copper concentrate in several large foreign concentrators are introduced. I believe that the current copper and molybdenum concentrate concentrate re-grinding and then re-election section using flotation column + conventional flotation machine combination of the principle of the process has matured; industrial production of flotation column equipment, large-scale, diversified shows the promotion and application of reliability.
