Prospect of mineral processing wastewater treatment technology

Mining waste is a mixed system, wherein the contaminants include suspended solids, pH, heavy metals and arsenic, fluorine, pharmaceutical processing, chemical oxygen species and some other contaminants such as oils, phenols, ammonium, phosphine Etc. Therefore, the treatment process for this kind of wastewater is to use organic technology in combination with each other, and in which the rational use of relevant resources in the mine should be considered, such as: alkaline tailings and acidic wastewater, lime in mines. The agent for adjusting the pH of the raw water and the precipitated agent. In the wastewater treatment process, pre-precipitation and coagulation-precipitation techniques can be used first to remove suspended solids, and then to consider the control technology of the remaining pollutants in the water. As for the sludge generated in the wastewater treatment process, if it contains available metal resources, it can be returned to the beneficiation process for re-sorting. If there are few useful ingredients, sludge dewatering and stabilization can be carried out, and then the conventional sewage can be used. Mud disposal technology for disposal.

When considering the resource utilization problem of wastewater, the corresponding treatment process can completely meet the standard of reclaimed water in the treatment of mining wastewater, and then reuse the unit of each water in the selection process, so that the recycling of water resources can be achieved. In addition to wastewater treatment and reuse, it is also necessary to consider the comprehensive smelting scheme of ore dressing wastewater, that is, in the process of mineral processing, innovating the process to minimize the amount of water used for production and the serious pollution to the environment. After the implementation of these measures, the wastewater generated during the beneficiation process can be rationally treated and recycled to achieve the purpose of comprehensive treatment of ore dressing wastewater, and meet the standards for clean production.
