| 中文摘要: |
| 河北省某金矿为氧化石英脉型金矿石,矿石中的金粒微细,平均粒径为0.011 3 mm,包裹于黄铁矿、褐铁矿、石英中的金占64.68%,有一部分呈微细粒包裹在土状褐铁矿中,对这种细粒分散的含金氧化矿石采用全泥氰化浸金工艺。将原矿磨矿细度确定为-200目含量占85%,加入石灰对金矿石进行碱预处理,再加入氰化钠浸金,取得了浸出率为96.89%,吸附率为99.55%的试验结果。 |
| 英文摘要: |
| Gold in the oxidized quartz vein type gold deposit occurs in micro-grain. The grain size is averagely 0.0113 mm. The gold enclosed in pyrite, limonite and quartz is about 64.68%, and some in earthy limonite. All slime syanidation leaching-out method is used to treat the gold ore. The raw ore is milled to fineness of -200 mesh 85%. The ore is pre-treated by adding lime into the ore then sodium syanide is put to leach out the gold with leach-out rate of 96.89% and absorption rate of 99.55%. |
