The same problem exists in the same ore body in the same mine, which brings great difficulties to the beneficiation operation. In order to separate the monomers of magnetite minerals to meet the technological requirements, the current process will inevitably use the smallest embedded particle size as the standard for grinding, which results in over-grinding of some minerals.
