  Beneficiation of Iron Ores – IspatGuru

  201443 · This is carried out by the processes of beneficiation of the iron ore. Beneficiation of the ore is the process where ore is reduced in size and gangue is separated from the ore. Since each of the iron ore deposit has a unique mineralogy, the beneficiation process is specific to each deposit.

  Dry beneficiation of iron ore - Mineral Processing

  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.
