At present, the common mineral processing wastewater treatment methods usually have two kinds of lime neutralization precipitation method and flocculation precipitation method. Lime neutralization precipitation method is often used in acidic mineral processing wastewater containing heavy metal ions, which can remove heavy metal ions while neutralizing the acid in the wastewater, and recover valuable metals from the precipitation residue. Flocculation sedimentation method by adding FeSO4 and alum and other flocculants, so that it and heavy metal hydroxide particles in the flocculation mode bridge chain, form a larger particle co-precipitation. In order to speed up the precipitation rate of heavy metal hydroxides and improve the precipitation efficiency, technological measures can be taken to strengthen the precipitation process, such as adding inclined plates and inclined tube devices in the sedimentation tank.
The above method can only remove the heavy metal elements and the solid substances in the mineral processing wastewater, and does not consider the treatment of the mineral processing agent in the wastewater. Oxidation, ion exchange, activated carbon adsorption, foam flotation, biochemistry, electrodialysis and ferrite method should be used for comprehensive treatment to remove the organic flotation agent while removing the heavy metal pollution.
From the beneficiation process and wastewater treatment methods, the most effective measure is to try to recycle tailings wastewater to achieve zero discharge and reduce the total amount of wastewater, followed by purification treatment.
