摘要

针对江西某钨钼矿生产指标不稳定、工艺技术指标偏低、能耗高等问题,对选厂给矿进行了分析,并进行了相应的选矿试验研究.研究发现给矿中的风化矿对选厂生产造成了极大的影响,风化矿的混入是造成钨精矿回收率大幅波动的主要原因.采用单独处理风化矿的方案,并避免风化矿混入原生矿的生产中,选厂的生产指标稳定,钨总回收率由原来的72%～73%提高至77%～80%,大大地提高了选厂的经济效益.
        Absrtact: The feed of the concentrator was analyzed and the beneficiation test was carried out in detail for the unstable production index, low technology index and high energy consumption of a tungsten molybdenum ore in Jiangxi province. It is found that weathered ore has a great influence on beneficiation concentrator production, and the mixing of weathered ore is the main reason for the large fluctuation of the recovery rate of tungsten concentrate. After adopting the scheme of avoiding mixing weathered ore in primary ore and deal with weathered ore separately, not only the production index is stable, but also the total recovery rate of tungsten concentrate is raised from the original 72%-73% to 77%-80%, which greatly improves the economic benefits of the plant concentrator.
