研究了应用聚合物分散剂作用于含5．30％和2．87％WO3的钨矿泥样的强磁选分离。研究表明，在较细矿泥中，WO3含量较多。精矿的品位比未用分散剂的有所提高。使用分散剂的强化磁性分离是借助于减弱颗粒间的杂凝聚作用。回收率与品位关系表明：1T的场强刚好足以吸引黑钨矿，这就导致比较高场强时的精矿品位更好，但是，以降低3％的回收率为代价。
The effect of polymer dispersant on the magnetic separation of tungsten slime containing 5.30% and 2.87% WO3 was studied. Studies have shown that there is more WO3 in the finer slime. Concentrate grade than non-dispersant has improved. Enhanced magnetic separation using dispersants is done by weakening the inter-particle heterocondensation. The relationship between recovery and grade shows that a field strength of 1T is just enough to attract wolframite, which leads to a better concentrate quality at higher field strengths, but at the expense of a 3% reduction in recovery.
