摘　　要：银洞坡金矿矿石物质组分复杂,不同矿体、同矿体不同部位氧化程度变化大,矿石品位属很不均匀类型,矿石含泥质较高,属难选型矿石。将浮选获得的金精矿(主要是低品位)与原矿(含泥量高不易浮选)混合配矿后氰化,达到解决低品位金精矿销售难,同时提高成品金生产能力,即避免单一金精矿氰化因贵液品位高,活性炭吸附不完全降低回收率的缺陷,并相应达到了提高氰化原矿品位和金的回收率,充分利用国家资源的目的。The component of the ore from Yin-Dong-Po Gold Mine is quite complicated.The oxidizability of different orebody and the same type orebody from different locations are different extremely.Due to uneven grade distribution and higher clay content, such kind of ore belongs in refractory mineral.Through mixing of gold flotation concentrate (the most are low graded ore) and run-of-mine ore (high clay content and difficult to conduct flotation) followed by cyanidation, the problem of bad sale for low graded gold concentrate of Ying-Dong-Po Gold Mine was solved. Moreover, it enhanced productivity of finished gold and excluded the defect of low gold recovery due to incomplete adsorption of gold by activated carbon from high graded cyanide pregnant solution of single type gold concentrate. Also,it raised the grade of run-of-mine ore and gold recovery.
