Experimental research on a zinc oxide ore Xuanye Guizhou performed. After a variety of experimental studies on mineral processing , zinc is still not enriched, and later changed to experimental research by smelting methods.
Rotary kiln treatment of zinc oxide ore technology is mature and reliable, and is often used in zinc oxide production. The process is short, the equipment is simple and easy to operate, but zinc oxide contains high impurities.
The wet treatment of zinc oxide ore technology is mature and reliable, and the oxidation dust is harmful to the environment, and the working conditions are better. The finished zinc oxide is better than the zinc oxide produced by the rotary kiln method.
The tested refractory ore is typically a zinc oxide ore, since the multi-containing soluble salts, containing a large quantity of mud (mud also zinc) and a surface quality iron oxides, or hydroxides or cover contamination, very conventional flotation process Difficult to float.
Due to the high iron content of the ore and the high iron content of the tailings, the tailings contain zinc and iron sometimes higher than the ore. It can be inferred that the zinc mineral is closely symbiotic with iron (the ore contains too much mud and can no longer be finely ground to make it monomer Dissociation) is either an iron-containing zinc mineral such as zinc iron spinel (Zn.Mn) Fe 2 O 4 or the like. If this is the case, the iron is selected by strong magnetic or other methods, and the zinc content is not high. The zinc iron spinel theory has a zinc content of 22 Zn%. Therefore, as a zinc mineral, this is of no practical significance. To make the zinc ore rich integrated product, it can be referred to hydrometallurgical processing or other methods after doing economic, technological considered.
