【摘要】 本文主要针对云南某铁锰矿的贫矿进行了选矿试验研究,并与该矿的富矿的选别效果进行了对比。在选矿试验的基础上,分别提出了贫、富矿处理的原则:贫铁锰矿可生产中矿;对于富矿的选别,采用粗磨跳汰-摇床的技术方案,得到的锰精矿品位为40.41%,回收率为70.92%的选别指标。更多还原

【Abstract】 The paper introduces the research of mineral processing test of somewhere’s low-grade ferromanganese ore in Yunan.Test results have been compared low-grade ore with high-grade ore.Based on processing test,the separate principles for low and rich-grade ore have been provided;we may produce middling product by this low-grade ore;For the rich-grade ore,we gain the concentrate ore containing Mn40.41%,the recovery rate of Mn is 70.92% by raw-grinding,jigging and shaking-table更多还原
