%X The invention provides a quality separation treatment classification reuse method of tungsten zinc polymetallic ore beneficiation wastewater, belonging to the technical field of metal ore beneficiation wastewater treatment. The method provided by the invention comprises the following steps: adjusting the pH value of raw ore roughing wastewater of tungsten zinc polymetallic ore, mixing it with defoamer and first flocculant, filtering and adsorption in turn, and then reusing the beneficiation process; The waste water of tungsten zinc polymetallic ore sulfide ore, defoamer and calcium remover are mixed for the first time, and then mixed with the second flocculant after adjusting the pH value. After filtration and adsorption in turn, they are reused in the beneficiation process; Adjust the pH value of oxidized ore wastewater of tungsten zinc polymetallic ore, mix it with defoamer and the third flocculant, filter and adsorb it in turn, and then reuse it in the beneficiation process. The method provided by the invention adopts the short process closed-circuit quality separation treatment and classification recycling process, constructs a interlocking short process quality separation classification nested recycling technology system, improves the reuse rate of beneficiation wastewater and reduces the unit water consumption.
