| 摘 要： | 查明了信阳某银矿主要矿物组成,银主要与各种硫化矿紧密共生,因此可以采用浮选硫化矿的方法富集银。通过浮选条件试验,确定了各项浮选工艺参数,浮选开路试验获得了Ag品位1251g/t,回收率88.08%精矿产品。浮选粗精矿经多次精选后,可获得Ag品位1758g/t,回收率为71.01%的最终精矿。

| Abstract: | On the basis of mineralogical study, silver minerals are closely associated with sulphide ores, and silver minerals could be concentrated by floating sulphide ores. According on the process parameters confirmed by floating condition tests, open circuit tests were carried on to gain the concentrate with Ag grade of 1251g/t and recovery of 88.08%. After couples of scavenger to roughing concentrates, good floating results were obtained with Ag grade of 1758g/t and recovery of 71.01%. |
