Abstract: Non-ferrous metal beneficiation wastewater is often acidic or alkaline, and contains a large number of residual reagents, suspended solids and metal ions-based pollutants. With the continuous development and utilization of mineral resources, non-ferrous metal beneficiation wastewater has become a major cause of mine environment, water and soil pollution. The wastewater from mineral processing can not be applied to mineral processing. This was accounted by the fact that all kinds of pollutants can damage mineral processing equipment, affect mineral processing flowsheet and decrease concentrate quality. Therefore, the comprehensive treatment of non-ferrous metal beneficiation wastewater has become an urgent problem that needs to be solved in China and even in the world. This article summarizes the treatment methods of the main pollutants that are generated from non-ferrous metal beneficiation wastewater, expounds the current research status of non-ferrous metal beneficiation wastewater treatment in recent years, looks forward to future development direction of wastewater treatment.
