Different materials possess different magnetic properties by which they may be separated. Figure 9.1a shows that when a magnet is placed close to an iron ball and a ceramic ball, the iron ball will be attracted to the magnet and the ceramic ball will not. Figure 9.1b shows that when a magnet placed close to a group of mixed tiny iron and …
Dry iron ore beneficiation is without doubt currently being driven forward by Vale in Brazil. The company wants to increase its capacity from 340 Mta iron ore at present to 450 Mta in future, dry beneficiation is to be further increased by 10 % from 60 % at present. Dry beneficiation capacity will increase by around 110 Mta.
