Zinc, oxide ores are first sulfurized with a sulfidizing agent, and then flotation is achieved by using cationic collectors (such as amines) or anion collectors (such as xanthate). The sulfidation process plays a dominant role in the sulfidation–flotation method, and the effect of sulfidation mainly depends on the mineral crystal structure, surface active components, etc [ 8 , 9 ].
