| 摘 要： | 某金精矿经焙烧预处理—酸浸—氰化浸金后,其提金尾渣金品位较高,在10 g/t左右。为查明该金精矿金回收率低的原因,对其提金尾渣进行了工艺矿物学研究。通过对提金尾渣的化学组成、相对矿物含量、主要矿物嵌布特征、金的粒级分布及赋存状态等的考察分析,指出了影响金回收率的主要因素,为金回收率的提高提供基础资料。

| Abstract: | After one gold concentrate is treated by a roasting pretreatment-acid leaching-cyanidation process, the tailings slag obtained has a high gold grade of near 10 g/t.Therefore,research on the process mineralogy is con-ducted of the slag from gold extraction to find out why the gold concentrates have a low gold recovery rate.Through the investigation on the chemical composition of the tailings slag,the relative mineral content,the disseminated characteris-tics of major minerals,the size distribution of gold particles,and the occurrence state of gold etc.,the paper finally pointed out that the main influencing factors of gold recovery,providing basic information for improving gold recovery rate. |
