山东某金矿石浮选试验

Flotation Experiments of a Gold Ore in Shandong

山东某低硫石英脉型金矿石中的金粒度较均匀,以裂隙金和包裹金的形式赋存于黄铁矿和石英中。对该矿石的磨选工艺技术条件研究表明:在磨矿细度为-0.074 mm占80%条件下,采用1粗2扫2精、中矿顺序返回流程处理,可获得金品位为61.33 g/t,回收率为93.73%的金精矿。

The gold particle in a quartz-vein type gold ore with low sulfur in Shandong is uniform granularity,and exists in pyrite or quartz,in form of fissure gold and inclusion gold.Research of the technical conditions for grinding and separation of the ore showed that under the grinding fineness of-0.074 mm 80%,gold concentrate with gold grade of 61.33 g/t,and recovery of 93.73% was achieved by the process of one roughing,two scavengings,two cleanings and middles back to the process in turn.
