 · After the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation.

Processed Iron Ore increases campaign life Fine particles and Alumina in the feed end up as accretions in the kiln walls. Lower Alumina in the feed means a considerable reduction in cleaning and maintenance of the kilns. CDE Wet Screening technology also ensures lesser dust accumulation in the dust cleaning system reducing its cost implications.
