在磷矿浮选中,为了提高脂肪酸类药剂的选择性捕收效果,国内外都进行了以脂肪酸为主的混合捕收剂的研究。最近美国氰胺公司的Samual S.Wang等连续发表了两篇有关专利,效果显著。虽然,用以与脂肪酸混合的药剂的来源和价格就我国目前情况看来未必合理,但对我们从事混合捕收剂的研究仍然不失其参考价值。 In the flotation of phosphate rock, in order to improve the selective catching effect of fatty acids, fatty acid-based mixed collectors have been studied both at home and abroad. Recently, Samual S. Wang, a U.S. company in Cyanamid, published two consecutive patents with remarkable results. Although the sources and prices of the agents used to blend with fatty acids may not be reasonable for our country’s current situation, the research on hybrid collectors remains intact.
