【摘要】 针对河南某难选钼尾矿再选技术的改进,利用正交试验表对浮选柱超声波预处理浮选系统进行了多参数测试。正交试验结果分析得出了超声波预处理的最佳参数组合,并选取两组优组合参数对试验结果进行验证。同时还通过对比试验进一步明确了超声预处理对目的矿物可浮性的影响大小,得出超声波预处理对微细粒矿物浮选具有促进作用的结论。更多还原

【Abstract】 As an effort to make improvements to the technology of re-flotation of a refractory molybdenum tailing in Henan Province,a multi-parameter test is carried out using orthogonal table L9(34) in the column flotation system with ultrasonic pre-treatment.Through analysis of orthogonal test results,optimum parameters of ultrasonic pre-treatment are acquired.In addition,optimal combination of parameters of two groups is selected to verify the test results.Furthermore,the impact of ultrasonic pre-treatment on the floatability of minerals are defined by comparison tests and the conclusion has hereby drawn that ultrasonic pre-treatment promotes the flotation of micro-fine minerals.更多还原
