提高黑钨重力选矿厂摇床选别效果的研究与实践

摘要

淘锡坑钨矿选厂通过加强矿物入选粒级控制和提高分级机分级效果等技改措施,提高了重选段摇床选别效果,使尾矿品位降低了0.07％,每年可多回收钨精矿140余t.%This article introduces the production practice of the dressing plant in Taoxikeng Tungsten Mine through controlling mineral particle size and improving classifier's classification effect to improve the beneficiation effect of gravity concentration shaking table. Recovery rate analysis shows the technical renovation is favorable for reducing the tailings grade. The net adding tungsten concentrates is 1401 annually.
