| 摘 要： | 以金川镍矿二矿区富矿矿石为研究对象,通过浮选试验、浮选动力学方程模拟和粒度检测,研究超声波作用对硫化镍矿物浮选行为的影响。结果表明,对磨矿后的矿浆,经超声处理后再进行浮选可以得到更高的镍品位和回收率;金川镍矿的浮选速率符合二级矩形分布动力学模型,超声波作用使得浮选速率常数显著提高,粗粒硫化矿物的浮选行为改善。

| Abstract: | The effect of ultrasonic on the flotation performance of nickel sulfide ores from the rich ores of Jinchuan No.2 mine area was studied through flotation tests,flotation kinetic equation stimulation and particle size measurement. Results show that higher nickel grade and recovery can be obtained by ultrasonic treatment followed by flotation. The appropriate flotation kinetics model of Jinchuan nickel mine flotation rate is the second-degree rectangular distribution model. Under ultrasonication, nickel flotation rate increases dramatically, and the flotation behavior of coarse sulfide is improved. |
