【摘要】 矿泥对金红石浮选影响大,为了有效地减少矿泥对金红石浮选的影响,进行抑制金红石反浮选试验研究。研究结果表明,采用硫酸铝抑制金红石,用油酸钠反浮选,而且油酸钠的添加采用逐点加药的方式,可以抛弃31.34%的泡沫产物,泡沫产物中金红石品位为0.39%,损失率低,为6.23%。槽中金红石的品位由1.96%提高到2.68%。反浮选后,活化金红石正浮选,一次浮选可以得到品位为20.30%,回收率为83.88%的金红石粗精矿。反浮选过程中,矿泥脱除效果好,-0.010mm粒级脱除率达到74.79%,为金红石的正浮选创造了有利条件。更多还原

【Abstract】 Slime has a great impact on rutile flotation. In order to efficiently reduce the slime effect on rutile flotation, test research was conducted on rutile depression in reverse flotation. The result shows that a froth product with a yield of 31.34% can be discarded in the reverse flotation with sodium oleate added by starvation method, where rutile is depressed by aluminum sulphate. The froth product of the reverse flotation has a rutile grade of 0.39%, leading to only a low rutile loss of 6.23%. The sand products has a rutile grade that is improved from original 1.96% to 2.68%, and is activated after the reverse flotation and treated by positive flotation, from which a rougher rutile concentrate grading 20.30% at a recovery of 83.88% is obtained. The reverse flotation can remove 74.79% -0.010mm fraction, creating a favorable condition for the positive flotation of rutile.更多还原
