铜、铅、锌氧化矿一般是先用硫氢化钠或硫化钠硫化后再浮选。但是,脉石为石灰石或白云石的氧化矿硫化浮选,有时就产生用普通方法难以解决的问题。因为这些脉石将有碍硫化的可溶性盐(Ca~(++)、Mg~(++)离子)带入矿浆,钙、镁离子使机械带入泡沫的石英细粒团聚,并极大地加剧有用矿物颗粒被磨矿过程中产生的白云石或石灰石矿泥覆盖的现象。这种矿泥不仅降低有用矿物浮游的选择性,而且强烈破坏其浮游性。采用丙烯酸聚合物作为调整剂来
Copper, lead, zinc oxide ore is generally the first with sodium sulfide or sodium sulfide and then flotation. However, the gangue is limestone or dolomite oxide ore sulfide flotation, sometimes resulting in problems that are difficult to solve by conventional methods. Because these gangue will hinder the sulfide salt (Ca ~ (++), Mg ~ (++) ions) into the pulp, calcium and magnesium ions into the foam of quartz fine particles agglomeration, and greatly exacerbated The phenomenon that useful mineral grains are covered by dolomite or limestone slime produced in the grinding process. Such slime not only reduces the selectivity of useful minerals in planktonic activity but also strongly destroys its floatability. Acrylic polymer is used as a regulator
