| 摘 要： | 矿石中主要回收元素为金,主要为自然金和金银矿且多包裹在脉石矿物中,裂隙金和粒间金分布较少。回收难度较大,对矿样进行了重选、氰化浸出及浸渣浮选试验,获得重选作业金回收率4.75%;氰化浸出作业金回收率51.00%;浸渣浮选作业金回收率为86.78%,金精矿含金40.85 g/t,金矿石的选矿总回收率为93.83%的较好试验指标。

| Abstract: | The gold is the main useful element in the ore, the nature gold and kustelite are main gold minerals,which are packed in gangue,and they are difficult to recover.The gravity concentration,cyanide leaching and flotation experiments are done and gain better results,the recovery of gravity concentration operation is 4.75%,recovery of cyanide leaching operation is 51%,and recovery of flotation operation is 86.78%, the grade of gold concentrate in flotation is 40.85 g/t,and the total recovery of gold is 93.83%. |
