Zinc mainly comes from zinc sulfide ore, but with continuous exploitation of resources, the demand for developing and utilizing zinc oxide resources is more and more urgent.
At present, the zinc oxide ore is mainly recovered by a sulfide-amine flotation method, but amine is sensitive to slime, mica and the like, particularly, the slime has negative electricity on the surface and can generate electrostatic adsorption with amine ions with positive electricity to consume a large amount of amine, and the property of the ore surface can be changed by the slime adsorbed on the ore surface, so that the selectivity is lost when a collecting agent acts on the ore surface, and the quality of concentrate is seriously influenced. A common solution to this problem is direct leaching or desliming flotation. However, the direct leaching method consumes a large amount of leaching reagents, and increases the production cost; the desliming flotation refers to the continuous adoption of a vulcanization-amine method for flotation after fine mud is removed, and still has the problems of high production cost and incapability of completely removing and recycling the fine mud.
