Luding Copper Mine Tailings Hydraulic Filling System
Copper Tailings Muding water filling system shown in Figure 1. The tailings of the Luding copper mine are graded by a ф125mm and ф300mm cyclone, and the content of the -0.037mm particles in the grit is 25%. In the sand bin, the slurry is made by water gun. The concentration of pulp is 50-60%. After entering the mixing drum, it is transported to the well by double-line. The ground of the pipeline is ф163×7mm, and the wind well is ф159×12mm.
