| 摘 要： | 广西某金矿区矿石为毒砂、黄铁矿化砂岩、泥岩含金矿石,含金品位仅0.91×10-6,主要有价金属元素为金,金主要赋存在载金矿物--黄铁矿和毒砂中。经过“一粗二扫四精”浮选流程并在精选作业采用Mf376 脉石抑制剂,得到了含金品位17.0×10-6 的金精矿,选矿回收率84.23%,富集比达到18.68 倍,获得了很好的选矿技术指标。

| Abstract: | The ore of one gold mine is containing-gold in the sandstone,mudstone with arsenical-pyrite and pyritization in Guangxi Province,gold grade is only 0.91× 10-6,and gold is the main element of valuable metals.Gold had occurred in gold-bearing mineral pyrite and arsenopyrite.Through flotation process of＂one roughing-separation,two scavenging-separation,four concentrations＂ and used Mf376 gangue inhibitors for concentration operation.We had a good indexes of mineral separating technology,gold concentrate containing 17.0×10-6,84.23% recovery of gold,18.68 times of enrichment-ratio. |
