Abstract

The invention provides a comprehensive recovery beneficiation method of tungsten / tin / zinc polymetallic ores. The method is characterized by comprising the following steps: the ores are crushed, grinded and reselected to obtain tungsten / tin / arsenic heavy-concentrate products; the flotation is performed for the heavy-concentrate products to obtain arsenic concentrates; flotation tailings are magnetically separated to obtain tungsten concentrates; magnetic separation tailings are tin concentrates; and the grinding and the flotation are performed for reselected tailings to obtain zinc concentrates. The method firstly performs the reselection to produce tungsten / tin / arsenic mixed concentrates, so that the flotation ore quantity and the flotation reagent dosage are reduced, and the advantages are provided to improve the tungsten / tin recovery rate and to reduce the scaling of a shaking table; and the arsenic flotation and the zinc flotation are separately performed, the types of flotation reagents are decreased, and the ore grinding cost is reduced.

Description

technical field [0001] The invention relates to a non-ferrous metal mineral processing method, in particular to a tungsten-tin-zinc multi-metal comprehensive recovery combined mineral processing method, which belongs to the non-ferrous metal mineral processing technical field. Background technique [0002] The associated zinc-arsenic ores of tungsten-tin ore can comprehensively recover various elements such as zinc and arsenic in addition to the main elements of tungsten and tin. Disseminated form is the main form, followed by dense massive form, and various minerals are embedded with uneven particle size, so it is more difficult to separate minerals. [0003] At present, the processing of such ores mainly adopts (1) flotation---gravity separation---magnetic separation process. That is: after the raw ore is crushed and ground, the sulfide ore is selected by flotation, the flotation tailings are re-selected to recover the tungsten-tin mixed concentrate, and the tungsten and ...
