Abstract

The beneficiation method for zinc oxide ore includes milling, lead oxide floating, 1-3 grade of fine grain roughing of the tailings after lead oxide floating, 1-3 times of beneficiation for each roughed concentrate, roughing the middlings of the last time and the middlings of the first beneficiation, and final precise floating to obtain the concentrate. The present invention solves the technological problem of floating muddy zinc oxide ore by means of first floating of small grains and then the large grains, and has high zinc oxide ore recovering rate, reduced zinc oxide content in the tailings, lowered floating agent consumption and effective utilization of muddy zinc oxide ore.A

Description

technical field

[0001] The invention relates to a beneficiation method, in particular to a beneficiation method of argillaceous zinc oxide ore. Background technique

[0002] At present, for argillaceous zinc oxide ore with high iron content, the limonite and goethite in it are easy to muddy after grinding and adhere to the surface of zinc oxide. When it is flotation, it is not easy to float; The second is that the consumption of reagents is large; the third is that the flotation time is long and the recovery rate is low. The prior art methods for flotation of argillaceous zinc oxide ore include: (1) heating, sulfidation of zinc oxide ore flotation, which not only consumes a lot of heat, but also is difficult to achieve better technical and economic indicators. (2) Sorting method of ore sand and ore slime, this method needs two processes, and the equipment that is equipped with is more, and the flotation reagent of ore slime consumes a lot, and the flotation time is long.
