iron ore grinding coarse

Mineralogical characterization of the typical coarse iron

Jan 15, 2019· To decrease the energy consumption in grinding coarse iron ore particles, the preliminary processing of run-of-mine (ROM) iron ore has become necessary to facilitate the subsequent upgrading and purification [11,12]. Gravity separation is an alternative approach to improve the quality of ROM iron ore by discharging waste gangue.
