内蒙古铁锡矿选厂同步尾矿回收工艺研究

Research on Synchronous Tailings Ore Recovery Process of Inner Mongolia Iron-Tin Concentrating Plant

针对内蒙古某铁锡矿选厂同步尾矿的特性，根据选矿试验的成果，提出了砂泥分选、集中脱杂、简化粗选及强化精选的新工艺，并对设备选型进行优化比较。生产实践表明，该尾矿回收工艺，可产出含锡35％～40％，回收率15％的锡精矿，含锡4％～5％，回收率10％的锡富中矿，基本达到了设计要求。

Aimed at rthe characteristics of synchrotron tailings of iron -tin ore concentrating plant in Inner Mon-golia .esearches and according to the results of mineral prosscessing test , the new technology of sand -mud sepa-ration, concentrated impurity removal , simplified roughing and strengthen selecting was presented and optimiza-tion for equipment selection was conducted .The production practice shown that the tin concentrate with 35%-40%tin-bearing and 15%recovery and .rich tin middlings with 4%~5%tin-bearing and 10%recovery can be produced by the tailings recovery process , which can basically meet the designed requirements .
