云台山硫铁矿提高硫回收率的研究与实践

Study on increasing sulphur recovery and its practice in Yuntaishan Pyrite Mine

分析研究了选厂综合硫回收率偏低的现状,通过粉矿生产工艺改造,利用提高粉矿品位和产量、把粉矿生产与选厂破碎工艺相结合、合理降低入选总硫量等一系列措施,大大改善了混合矿配比和质量,使综合硫回收率提高到92.60%,增产降耗效益近150万元/a。

The status of low general sulphur recovery in the beneficiation plant was analyzed. Based on the reformation of powder ore production process, the quality and change ratio of mixing ore was improved. The general sulphur recovery was increased to 92.60%.
