Dry beneficiation of iron ore
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.

Mineral beneficiation and ore dressing
The crushing process is by the run-of-mine, whereas the ground, i.e. the second step after crushing, is on dry material. Heavy forces such as compression, impact (mainly for crushing) and attrition (mainly for grinding) are responsible for crushing or grinding. Crushing and drying are slightly different, as crushing involves a drying process.
