Mineral Processing Wastewater Treatment and Reuse Equipment
Various metal mines such as iron ore and copper ore require crushing, screening, and grinding processing after ore extraction. After being processed into fine powder, they undergo concentration using different processes, but most adopt hydraulic selection, which generates a large amount of wastewater and seriously pollutes the surrounding environment.
Tangshan Shengshi Environmental Protection Equipment Co., Ltd. treats mine wastewater using a process that combines primary sedimentation, secondary flocculation sedimentation, and sand filtration, achieving resource recovery and reuse. On one hand, this enables the mine to achieve zero wastewater discharge. On the other hand, the treated wastewater is recycled, saving a large amount of water resources. Both sedimentation stages use high-efficiency vertical flow sedimentation tanks. Primary sedimentation first removes larger particles with greater specific gravity, while secondary sedimentation, under the action of flocculants, removes smaller particles with lower specific gravity that are harder to settle. The water then undergoes sand filtration, resulting in effluent that meets the design standards. By separating primary and secondary sedimentation and relying on physical sedimentation for large particles, the process reduces chemical agent consumption. The entire process is characterized by good treatment efficiency, stable operation, and low chemical dosage.
The entire process adopts PLC automated control, with automatic monitoring of various operating parameters such as water level, water pump, and dosage. It runs stably and is easy to manage.
