Iron Ore Reduction

The research on the reduction of iron ore has received much attention in the past few decades as a result of the increasing cost and low availability of raw materials. The reduction of gaseous emissions and the search for low-cost alternatives to traditional routes has also boosted the investigations for reduction processes ( Plaul et al., 2009 ).

KINETICS OF IRON ORE REDUCTION BY COAL AND CHARCOAL

Iron is extracted from its ore, and is almost never found in the free elemental state. In order to obtain elemental iron, the impurities must be removed by chemical reduction. The possible ways of iron ore reduction: Industrially iron is produced from iron ores 2O3

Fine Grinding Of Iron Ore

Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation. Practice varies, depending upon the type of ore and the amount of reduction required.
