Method for treatment and recycling of beneficiation wastewater of polymetallic copper-lead-zinc ores in high altitude areas

The invention provides a method for treatment and recycling of beneficiation wastewater of polymetallic copper-lead-zinc ores in high altitude areas aiming at the beneficiation wastewater of the polymetallic copper-lead-zinc ores in high altitude areas, coagulating sedimentation or natural sedimentation is adopted at first and then oxidization aeration by means of ClO2 is carried out, pH value is adjusted, sedimentation is performed and the wastewater is recycled for the production of mineral beneficiation. The method greatly reduces use amount of water for mineral beneficiation, and the beneficiation wastewater after the treatment is recycled for the production with excellent mineral beneficiation indicators, the invention provides a new method and initiates a new way for the treatment and the recycling of beneficiation wastewater of polymetallic copper-lead-zinc ores.
