某含砷含碳微细粒嵌布难处理金矿石选矿试验

Mineral Processing Investigation of the Arsenic and Carbon Bearing Micro-fine Particle Gold Primary Grain

为了给某含砷含碳微细粒嵌布难处理金矿石开发利用提供依据,根据矿石性质试验采用了原矿细磨后直接氰化浸出,浮选预处理后尾渣氰化浸出,氧化焙烧预处理后烧渣氰化浸出工艺进行试验。试验结果表明采用氧化焙烧-烧渣氰化浸出工艺可获得83.45%金浸出率。

In order to utilize and exploit the arsenic and carbon bearing micro-fine paeticle gold primary grain, process test of cyanide leaching after fine grinding, flotation process with the cyanide leaching of tails and pretreatment of oxidizing roasting with cyanide leaching, were employed according to the characteristic of ore. The experiment result proved that leaching recovery of gold was 83.45% employed pretreatment of oxidizing roasting with cyanide leaching.
