| 摘 要： | 为了解决铝土矿反浮选中微细粒浮选的难题,设计出一种旋流浮选器,利用流体动力学理论,通过模拟计算,建立旋流浮选器中铝土矿的分离粒度模型,推导出旋流浮选器应用于铝土矿反浮选的理论依据。对河南某铝土矿进行旋流浮选器浮选实验研究。结果表明:通过优化调整旋流浮选器的条件参数,不预先脱泥直接进行铝土矿反浮选,最终获得满足拜耳法对铝土矿生产要求的一水硬铝石精矿,精矿中平均A/S为8.38,回收率为85.16%。

| Abstract: | In order to resolve the problem of fine particle flotation in the reverse flotation of bauxite,a new type of air-sparged hydrocyclone was designed,through accurate analog computation based on hydrodynamics theory.The theoretical foundation was deducted for the application of air-sparged hydrocyclone in the bauxite reverse flotation.The flotation tests of air-sparged hydrocyclone aiming at a bauxite from Henan province were studied.The results show that a diaspore concentrate directly used in the Bayer-miner... |
