Gold mine tailings paste filling is a common mining filling method aimed at solving the problem of tailings pollution in gold mining. By mixing tailings with cementitious materials and water to produce a paste, and using a paste pumping filling method, efficient and environmentally friendly filling operations can be achieved. The paste filling system usually includes paste mixing equipment, paste conveying pipelines, paste storage equipment, paste pumping equipment, etc. These devices are capable of delivering the paste to the designated location and ensuring the stability and reliability of the filling process. The preparation of paste requires controlling the ratio of cementitious material and water to achieve the required filling effect. The filling of tailings paste can reduce the discharge of tailings, lower environmental pollution, improve mining efficiency, and reduce costs. However, when implementing tailings paste filling, it is necessary to consider the accuracy of the selection, preparation, transportation, storage, and control of filling materials to ensure the filling effect and safety requirements.
