Dry beneficiation of iron ore
Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.
