| 摘 要： | 为脱除电解铝渣中的炭质并回收有用组分,实现矿物的综合利用,通过浮选试验,考察不同球磨时间和不同种类捕收剂对电解铝渣尾矿中脱除炭质效果的影响,并确定最佳的试验条件。结果表明:在球磨时间15 min,捕收剂乳化油用量4 kg/t,起泡剂2#油用量4 kg/t的条件下,经过"1精3扫"试验流程可将尾矿灰分提升至97.38%。处理后的电解铝渣可作为助熔剂在电解铝的工业生产中被二次利用。

| Abstract: | In order to remove carbon from electrolytic aluminium slag and recover useful components to realize comprehensive utilization of minerals, the effect of milling time and different kinds of collectors were investigated through flotation tests, and the optimum test conditions were determined. The results show that the ash content of tailings can be increased to 97.38% through the process of "1 cleaning and 3 scavenging” under the conditions of 15 min milling, 4 kg/t emulsi fied oil and 4 kg/t 2 # oil. The treated electrolytic aluminium slag can be used as a cosolvent in the industrial production. |
