某选厂井下残矿锡石回收工艺流程的设计及生产实践

A downhole residual ore dressing plant, cassiterite recycling process design and production practice

铜坑矿井下残矿矿石性质较为复杂,含杂物较多,给分选带来了难度。通过对铜坑矿井下残矿进行预先隔粗除杂、破碎磨矿后,采用"重—浮—重"选矿原则流程进行分选,能够得到较好的生产指标,有价锡金属得到较好地回收,减少了矿产资源的流失。

The copper mine residual mineral ore properties is relatively complex, containing impurities is more, brings difficulty to sorting. Through to the copper mine residual ore to separate coarse in advance after removing impurity, crushing grinding, using ＂heavy - floating-heavy＂ separation principle of ore dressing process, can get better production index, marketable tin get better recovery, reduce the loss of the mineral resources.
