摘要
甘肃某卡林型氧化金矿石中金以微细粒包裹赋存在硫化矿、氧化铁矿、碳酸盐、硅酸盐等矿物中,采用全泥氰化和浮选工艺处理,金回收率很低。通过探索试验,确定采用焙烧—氰化工艺处理,在试验确定的最优条件下,金氰化浸出率可达到92%,取得了理想试验指标。
Oxide gold ores in this carlin-type gold deposit in Gansu province occur in superfine form embeded in sulfide ores, ferrous oxide ores, carbonate, silicate and so on. Poor gold recovery is only to be achieved when all sli- ming cyanidation and flotation are applied. Through exploratory experiments, a process of roasting-cyanidation is se- lected, in which, under optimisedconditions, gold recovery can reach 92 %.
