Treatment of mineral processing agent wastewater

There are usually two treatment methods for mineral processing agent wastewater: flocculation sedimentation and lime neutralization sedimentation.

The flocculation sedimentation method adds flocculants such as FeSO4 and alum to bridge with heavy metal hydroxide particles in a flocculation mode to form larger particles for common precipitation. In order to accelerate the precipitation rate of heavy metal hydroxides and improve the precipitation efficiency, process measures can be taken to strengthen the precipitation process. The lime neutralization sedimentation method is often used for acidic mineral processing wastewater containing heavy metal ions. At the same time, it can remove heavy metal ions and recover valuable metals from the precipitated slag. For example, inclined plates and inclined tubes are added to the sedimentation tank.

The above method only removes heavy metal elements and solid substances in mineral processing agent wastewater, without considering the treatment of mineral processing agents in wastewater. Oxidation, ion exchange, activated carbon adsorption, foam flotation, biochemistry, electrodialysis and ferrite methods should be used for comprehensive treatment to remove heavy metal pollution and organic flotation agents.

From the perspective of mineral processing and wastewater treatment methods, the effective measure is to try to recycle tailings wastewater as much as possible, achieve zero discharge, reduce the total amount of wastewater, and then purify it.
