The route of reverse flotation is currently in widespread use in iron ore flotation practice. The majority of studies on reverse flotation of iron ore focused on reagents and reagent scheme [9,10,11,12,13]. The reverse flotation route can be classified into reverse Desilication Application and Defoaming Mechanism of XK ,2021-6-21 · The study explored a new combination amine collector (XK-28) that can obtain better flotation index and defoaming rate for magnetic iron ore. A pure quartz mineral test indicates that dodecylamine, XK-I, or XK-II has good collection effect on quartz and their best flotation pH is in the range of 6–7. The experimental results of a combination collector (XK-I:XK-II = 2:8.) show that the
