| 摘 要： | 在研究矿石性质的基础上, 利用新型微泡浮选柱对河南某中低铝硅比铝土矿进行了实验室分选研究, 考察了捕收剂、抑制剂、充气量和淋洗水对分选结果的影响。闭路试验结果表明, 在优化条件下, 采用新型微泡浮选柱可得到精矿铝硅比为10.26, 氧化铝回收率87.24%的实验指标。试验证明新型微泡浮选柱对细粒铝土矿分选有良好的应用前景。

| Abstract: | Based on the analysis of mineral properties,a new type of micro-bubble flotation column was used in a laboratory study on beneficiation of a middle-low grade bauxite from Henan Province.The influence of collector,depressant,aeration rate and eluent flow rate on the separation effect was investigated.The results of the close-circuit test show that,under the optimized conditions,the A/S ratio for the concentrate can be enhanced to 10.26 and the aluminum recovery can be increased to 87.24%,which testifies that... |
