britannicaHow is Vale converting iron ore beneficiation to dry processes?Vale is endeavouring to switch its iron ore beneficiation largely to dry processes. The gangue types like silica is separated from the up to 15 % moist ore from the surface mines by means of dry screening (Fig. 7), with no water being added to the process. This is enabled by newly developed vibrating screens.Dry beneficiation of iron ore
