摘要
湖南柿竹园复杂低品位多金属矿中白钨矿回收,根据其工艺矿物学特性,先采用常温浮选工艺流程获得白钨粗精矿,再将粗精矿进行加温精选,加盐酸酸浸,最终获得了白钨精矿品位69.17%、回收率76.39%的良好试验指标。
The Recovery of scheelite from a complex low-grade multi-metal ore of Shizhuyuan Mine in Hunan was studied based on process mineralogical characteristics of the ore. First,flotation at room temperature was applied to obtain a rough concentrate,then cleaning floatation of scheelite was carried out at elevated temperature followed by leaching with hydrochloric acid. A scheelite concentrate grading 68. 95% WO3 with a recovery of 67. 22%was obtained.
