Abstract: The wastewater produced in the mineral processing process not only has a great influence on the environment around the mining area, but also has a certain influence on the concentrate quality when the mineral processing agent and heavy metal ions are reused in the mineral processing wastewater. The influence of mineral processing wastewater on environment and mineral processing process were analyzed by summing up the relevant literature. The coagulation and precipitation method, the adsorption method, the chemical oxidation method, the chemical precipitation method and the microbial treatment method and their advantages and disadvantages were summarized. This paper introduced new methods of treating mineral processing wastewater in laboratory in recent years. In the future, the development trend of mineral processing wastewater treatment is to gradually adopt multiple treatment methods instead of a single treatment method, and gradually adopt environment-friendly and low-cost treatment methods.
