Considerations for Beneficiation of Low Grade

Very low grade iron ore cannot be used in metallurgical plants and needs to be upgraded to increase the iron content and reduce the gangue. Iron ore is being beneficiated all round the world to meet the quality requirement of iron and steel plant. Use of iron and steel is increasing yearly as a result of upcoming projects all over the world.

ANALYSIS: The complicated growth of the 58%

Grade depletion at mines producing 62% Fe material – and the recent start-up of a wave of large-scale, lower-grade iron ore projects – has shifted that dynamic. The market for 58% Fe iron ore has now, in 2014, come to account for around 300 million tpy of an annual seaborne market that exceeds 1 billion tpy.

Iron Ore - Department for Energy and Mining

Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.
