浮选柱继续显示出比其它浮选方法更好的选别效果和经济效益。在美国伊利诺伊州罗西克莱尔的奥扎克-马奥宁公司的半工业试验中采用了两台浮选柱:一台直径为2.3m,用于锌粗选,另一台直径为1.1m,用于锌精选。该工艺流程取代了一段机械粗选-扫选和两段精选。概述浮选柱继续威胁着传统上占统治地位的机械浮选槽。例如,浮选柱作为粗选设备的作用越来越明显。加利福尼亚罗亚尔芒延金矿(RoyalMountain King Mine)浮选柱,用于从金矿中粗选碳。另外,法国地质和矿物勘探局(BRGM)的研究工作表明,浮选柱在设计方面优于机械浮选槽。
Flotation columns continue to show better selectivities and economic benefits than other flotation methods. Two flotation columns were used in the semi-industrial test at the Ozark-Maunoun Company in Rochester, Illinois, USA: one with a diameter of 2.3 m for roughing with zinc and the other with a diameter of 1.1 m, For zinc selection. The process replaces a mechanical roughing - sweep and two sections of the selection. Overview Flotation columns continue to threaten traditionally dominant mechanical flotation cells. For example, the role of flotation column as a rougher equipment becomes more and more obvious. The RoyalMountain King Mine, California flotation column is used to coarsely select carbon from gold mines. In addition, research by the French Geological and Mineral Exploration Agency (BRGM) shows that flotation columns are superior in design to mechanical flotation cells.
