Description

Technical field: [0001] The invention relates to a slag-copper separation device, which belongs to the technical field of slag-copper separation in the grinding process. Background technique: [0002] At present, the existing beneficiation process is two-stage open-circuit crushing, two-stage continuous grinding, and one-coarse, two-fine and three-sweeping separation processes. Affected by the smelting process, the blowing slag has strong magnetism and contains more large particles of bright copper. Due to the good ductility of metal copper, it is not easy to grind finely, resulting in the continuous circulation and accumulation of large particles of bright copper in the first-stage grinding process, resulting in the continuous circulation and accumulation of large-particle bright copper in the first-stage grinding system, and the grinding efficiency is reduced. Flotation Issues such as the increase in the dosage of chemicals and the increase in the grade of tailings have b...

AI Technical Summary

Problems solved by technology

[0003] (1) With the progress of production, the wear and tear of the pump increases and the service efficiency decreases. The maintenance period changes from 120 days to 90 days. In serious cases, the pump is blocked and must be temporarily stopped for maintenance, which restricts the grinding production;

[0004] (2) The continuous circulation and accumulation of large particles of copper in the ball mill caused the reduction of grinding efficiency, and the unit processing capacity of the mill dropped from 5t / h to 4.85t / h, and in severe cases it was less than 4.7t / h;

[0005] (3) Due to the continuous circulation of bright copper, part of the too finely ground bright copper enters the flotation process together with the pulp, and the amount of flotation reagents increases from 150g / t to 180g / t, which is not conducive to the recovery of the target minerals , causing the flotation tailings index to increase by about 0.04%

However, if magnetic separation equipment is added before ore grinding, the site space requirements are high, the construction is difficult, the cost is high, and it will affect the existing process flow and technical parameters, so it is unreasonable to use magnetic separation equipment before ore grinding
