某铁帽型含金复合矿综合开发利用新工艺研究

A NEW TECHNIQUE OF COMPREHENSIVE UTILIZATION FOR GOOSAN TYPE-GOLD COMPLEX ORES

提出了将矿粉配入A型添加剂及煤混合压制团块，直接还原－磁选分离－含金尾矿氰化浸出新工艺。采用该工艺处理某铁帽型含金复合矿，可直接从矿石提取金和海绵铁两种产品，达到了合理综合开发利用该矿的目的。

A new technique of the direct reduction for briquttes containing A-type additive,ore particles and coal, then magnetic separation and An-bearing tailings cyanidation has been suggested in this paper. Using this method, the goosan type-gold complex ores were processed, and then both An and sponge iron were obtained directly. Therefore, the goal, the comprehensive utilization of this type ores, could be achieved.
