钼离子浮选的优良工业生产结果,导至了对钨的离子浮选的研究。由于捕收剂的性质是决定离子浮选效率的主要因素,所以曾经系统地研究过不同组成和结构的含氮阳离子捕收剂ΠAB(伯胺、仲胺、叔胺、季胺盐和吡唑硷)的浮游性,并确定相应的聚钨酸盐的溶解度。这些研究结果,部分已发表。表明钨离子浮选的合适PH值为3—4,wo_3的初始浓度为0.1—1.0克/升,捕收剂性能最好的是含碳C_(10-13)的伯胺。
The excellent industrial production of molybdenum ion flotation led to the study of the ionic flotation of tungsten. Since the nature of collectors is a major factor determining the efficiency of ionic flotation, nitrogen-containing cationic collectors ΠAB (primary, secondary, tertiary, quaternary ammonium and pyrazoles) have been systematically studied Alkaline), and determine the corresponding polytungstate solubility. Some of these findings have been published. It shows that the suitable pH value of tungsten ion flotation is 3-4, the initial concentration of wo_3 is 0.1-1.0 g / L, and the best collector performance is the primary amine containing carbon C 10-12.
