白钨矿本身具有良好的浮游性。用普通阳离子捕收剂——脂肪酸及其皂类就很容易浮游。伹当矿石里含有和它本身浮游性相近的方解石、重晶石吋,就使浮选难以进行。在使用油酸做捕收剂时,白钨矿、重晶石、方解石浮游特性如图1。当我們做某钨銅矿的矿石可选性研究时,使用油酸做捕收剂,大量方解石进入泡沫产品中,严重地影响精矿品位,更重要的是回收率太低。因此,用浮选法处理复杂型白鎢矿,需要加强对浮游性相近矿石的选擇抑制作用,在粗选时除去大量方解石得出較高品位的粗精矿,給精选打下良好基 The scheelite itself has good floatability. With ordinary cation collector - fatty acids and soaps are easy to float.伹 When the ore contains calcite similar to its own floating, barite, it makes the flotation difficult. In the use of oleic acid collector, scheelite, barite, calcite floating characteristics shown in Figure 1. When we do a tungsten ore ore selectivity study, the use of oleic acid as a collector, a large number of calcite into the foam products, seriously affect the concentrate grade, more importantly, the recovery rate is too low. Therefore, the flotation method for the treatment of complex scheelite, the need to strengthen the selective inhibition of similar ores of the buoyancy in the coarse selection removed a large number of calcite to obtain a higher grade of crude concentrate, to lay a good selection of good
