据研究，用离子浮选法除去矿山废水中的金属离子是可能的。含有50mg/l铜离子的露采矿山废水可以得到净化。废水中的金属离子与黄原酸盐结合形成螫合物，而得到沉淀，这些螯合物具有较高的疏水性。在足够大的容器，具有高分散度的溶液内，利用电解浮选可获得气相。要实现沉淀和吸附胶粒浮选过程，要建立某些条件，采用表面活性剂油酸钾稳定所形成的泡沫层，它还带有沉淀剂的主要作用，改善沉淀过程，这样可除去废水中的金属离子。
According to the research, it is possible to remove metal ions in mine wastewater by ion flotation. Dew mining waste water containing 50mg / l copper ions can be purified. Metal ions in wastewater combine with xanthates to form complexes that give precipitates, which are highly hydrophobic. In sufficiently large vessels, solutions with a high degree of dispersion, gas phase can be obtained by electrolytic flotation. To achieve precipitation and adsorption of colloidal flotation process, to establish certain conditions, the use of surfactant potassium oleate stabilized foam layer formed, it also with the main role of precipitating agent to improve the precipitation process, which can remove the wastewater Metal ions.
