| titleOfInvention | A kind of treatment method of mineral processing wastewater |
| abstract | The present invention provides a method for treating mineral processing wastewater. The processing method comprises the following steps: pretreating the mineral processing wastewater to a turbidity of less than 10 NTU, and then illuminating for 1-18 hours under sunlight with an illumination intensity of not less than 0.2 mW/cm 2 , so that the Said beneficiation wastewater contains sulfur-containing carboxylate and/or nitrogen-containing carboxylate beneficiation agents; said sulfur-containing carboxylate beneficiation agents are dithiolactate, dithiosulfonate, dithiolate One or more of citrate and modified guar gum; the nitrogen-containing carboxylate beneficiation agents are dimethyl dithiocarbamate, diethyl dithiocarbamate, One or more of dibutyldithiocarbamate. The treatment method of the invention can effectively reduce the concentration of the agent in the beneficiation wastewater to the reuse standard, or even completely degrade, and the treated wastewater can be directly reused in the beneficiation process. The method is more efficient, environmentally friendly and cost saving. |
