• Hydrocyclone
• Sediment yield
• Structural parameter
• Tailings

Through the analysis of the optimal structural parameters of the hydrocyclone, the effects of the cone angle, the feed section material, the diameters of the overflow pipe and grit mouth, and the length of the overflow pipe on the graded yield of the tailings of the lead and zinc ore are discussed. The results show the change of the grit rate under different cone angle, feed section material, and length of overflow pipe. . The results show that the 10 degrees single cone hydrocyclone has the greatest influence on the graded yield of tailings, and the SiC material is less likely to be worn out under the condition of 21% feed concentration. And the graded sedimentation rate of the cyclone is more obviously affected. When the diameter of the overflow pipe is 20 mm and the diameter of the grit mouth is 48mm, the length of the overflow pipe is 285mm, the highest rate of cyclone grading is up to 49.37%. This test has some reference value for improving the hydrocyclone grading and the mining efficiency of mine. ? 2019 Multipurpose Utilization of Mineral Resources.
