Example Embodiment
[0055]As a preferred embodiment of the present invention, the copper sulfur primary mine is grinded to prepare a slurry.
[0056]Since the copper sulfur mine is mostly a block or granular shape, it is not conducive to the subsequent flotation process, so it needs to be polished.
[0057]As a preferred embodiment of the present invention, in step (a), copper sulfur mine is ground to fineness -0.074 mm accounted for 50-85%.
[0058]As a preferred embodiment of the present invention, in step (a), the mass concentration of the slurry is 30-45%.
[0059]The mass concentration of the slurry is too low, and it is easy to cause large drug consumption and affect the recovery of copper concentrate; the mass concentration of the slurry is too high, it is easy to cause inclusion, affecting concentrate position. Therefore, the mass concentration of the slurry needs to be controlled within a particular range. Typical but non-limiting minerals have a mass concentration of 30%, 32%, 34%, 35%, 38%, 40%, 42%, 44...
