赖特山(Mount Wright)选厂浓缩机底流尾矿的油酸浮选表明,可使该厂的回收率增加3%。这里需要添加大量的油酸(1.5公斤/吨),结果限制了该方法的经济实效。然而,从技术砚点看,这种处理法就油酸需要量、矿浆pH值和矿浆温度的最大波动来说是稳定的。必须发现一些可以降低油酸平均消耗量的方法。一种有进一步试验价值的方法是采用“背负”原理把细粒赤铁矿和粗粒赤铁矿颗粒一起浮起。
Oleic acid flotation of the bottom stream tailings at the concentrator mill at Mount Wright has shown a 3% increase in plant recovery. The need to add a lot of oleic acid (1.5 kg / tonne), the results limit the economic effectiveness of the method. However, from a technical point of view, this treatment method is stable with respect to the maximum amount of oleic acid required, the pH of the pulp and the temperature of the pulp. We must find some ways to reduce the average consumption of oleic acid. One way to further test the value is to float the fine-grained hematite with the coarse-grained hematite particles using the “carry-on” principle.
