iron ore processing by thermal treatment

Iron Ore | Geoscience Australia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.

In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders – practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.

Iron Ore Processing By Thermal Treatment

Further processing involves the agglomeration and thermal treatment of the concentrate to produce pellets that can be used directly in blast furnaces, or in direct reduction steel-making plants. The pellets contain 65% to 70% iron, which is a higher iron grade than the hematite DSO currently being exported from the Hamersley region.
