A beneficiation experimental research is conducted on sulfur-containing 10.57% lead-zinc tailings from Fujian. On the basis of the traditional mineral processing technology, the first is pre-classification by high-frequency vibrating, and then flotation-magnetic united technology. Eventually, the average grade of sulfur concentrate is 43.51% with comprehensive recovery 89.33%. The lead-zinc tailings get a comprehensive utilization, which has a better effect.

A beneficiation experimental research is conducted on sulfur-containing 18.17% multi-metals tailings. On the basis of the traditional mineral processing technology, it introduces X-51, a new type sulfide mineral activator, to instead of copper sulfate. Eventually, the sulfur concentrate grade is 47.51% with the recovery of 92.11%. The effectively recovery of the sulfur is creating good economic benefits and environmental benefit.

Cut And Fill

For mining using the caving and filling methods in metal mines, determining a suitable size for the isolated pillars—the connecting part of the extension from shallow to deep—is crucial for ensuring safety and efficiency. Considering actual cases involving deep caving and cut-and-fill mining in the Chifeng Hongling lead-zinc mine in Inner Mongolia, China, the reserved thickness range of the horizontal isolation layer is obtained via theoretical analysis. On this basis, the pre-processing software HyperMesh is used to build a high-precision hexahedral grid model of the mining area, and the three-dimensional geological model of the mining area is imported into the finite-difference software FLAC3D. The stress field, displacement field, and plastic area evolution law of pillars (horizontally isolated pillars and adjacent rib pillars) in the stope of the ninth middle section after excavation are analyzed via numerical simulation inversion of the selected scheme of horizontal isolated pillars. The numerical simulation results show that the scheme employed to retain the upper horizontal isolated pillars in the ninth middle section involves reserving thicknesses of 8 m and 32 m at average ore body thicknesses of 15 m and 35 m, respectively. These results can provide theoretical guidance and a basis for safe and efficient mining of deep metal mines.
