A Look at the Process of Pelletizing Iron Ore for Steel

Iron ore must go through a lengthy preprocessing stage before it can be pelletized a series of steps that work to beneficiate and concentrate lowgrade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

ANALYSIS The complicated growth of the 58% Fe iron ore

Grade depletion at mines producing 62% Fe material and the recent startup of a wave of largescale, lowergrade 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.

For this purpose, different beneficiation techniques such as gravity and magnetic separation processes have been employed. During the process two conceptual flow sheets were also developed for the

Iron ore pricing explained Metal Bulletin

For these reasons, the rule of thumb is higher Fe grade, higher price. Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.

Taconite

History. In the late 19th and early 20th centuries, the United States was mining such an abundance of iron ore of high quality that taconite was considered an uneconomic waste product. By the end of World War II, however, much of the highgrade iron ore in the United States had been exhausted. Taconite became valued as a new source of the metal.
