| 中文摘要: |
| 双朋西金矿床物质组成复杂,金属矿物以金属氧化物为主,含少量硫化物。载金矿物主要有褐铁矿、碳酸盐和石英,金矿物以自然金和银金矿独立矿物形式存在,以粗粒金为主,以裂隙金为主要赋存形式。根据金的化学物相和解离分析,选矿时加强细磨可提高金的回收率,选用浮选氰化工艺金的回收率可达91.7%。 |
| 英文摘要: |
| Material composition of the Shuangpengxi gold deposit is complicated with abundant metal oxides and a few sulfides.The main gold-carriers are limonite,carbonate and quartz.Electrum and native gold are the individual gold minerals.Gold is mainly in coarse grain size and hosted in mineral fractures.Fine grinding can raise the recovery of gold.The recovery of floatation+syanidation technology is 91.7%. |
