摘要:

针对某金矿石含泥质及贫连生体较多,金嵌布粒度细等特征,应用旋流器对浮选粗精矿进行分选,组成浮选—旋流器分选联合流程,取得了良好的效果。工业生产结果表明:采用旋流器对浮选粗精矿进行选别,能提早、高效地回收浮选粗精矿中大部分单体金和含金黄铁矿,提高金回收率;采用短锥旋流器分选,金回收率比采用分级用水力旋流器更高,可提高到75.04 %。

Abstract:

In light that a gold ore contains much slime and many barren and associate bodies and gold dissemination particle size is fine,cyclone is used for flotation roughing concentration grading composing a flotation-cyclone grading joint flowsheet and achieves good outcome.Industrial production results show that it can quickly and efficiently recover most monomer gold and goldbearing pyrite from flotation roughing concentrates and improve gold recovery rate to use cyclone for grading of flotation roughing concentrates.The shortcone cyclone can achieve better gold recovery rate than grading hydraulic cyclone,which is 75.04 %.
