超声波对浮选柱选钼过程中细粒尾矿再选的试验研究

Effects of Ultrasonic Treatment on Column Flotation of Fine Molybdenum Tailings

较多研究结果表明超声波对硫化矿物的选别影响显著,文中选择河南某辉钼矿作为试验对象,将原工艺流程中精扫选I的尾矿作为试验给矿进行超声处理,同时检验超声波的去泥效果。采用正交试验方法研究超声波各因素对选矿效率的影响及各因素间影响的显著性,并通过单因素方差分析评价了超声波有无对钼选矿效率的影响显著性。研究还表明超声波去泥效果显著,精矿中+38μm矿物的含量比无超声时增加了20.22%。

It is found that the effects of ultrasound on sulfide minerals are notable. In this paper, the Molybdenite in Henan, which is te metallic sulfide ore, have chosen as the test object. At the same time, in order to test the performance of removing sludge, the railings of concentration scavenging I in the previous process are treatde by ultrasound as the primary ore. An orthogonal experiment is carride out to investigate the impact of various factors of ultrasound on mineral processing efficiency and the significance of these impacts. Single-factor analysis of variance is conducted to evaluate whether ultrasound has significant impacts on the efficiency of molybdenum beneficiation. Additionally, the research indicates the sludge could be removed remarkable during process of molybdenum concentrate by ultrasound, the mass of＋38 p,m particles of concentrate raise up by 20.22% compared with those without ultrasound.
