We observed that, particle size decreased significantly due to regrinding while floatability of the feed was more than discharge. Moreover, floatability of each fraction ( 400, +400325) in mill feed and discharge was studied. Results indicated that, the floatability of all fractions in the mill feed was more than the mill discharge.

But, the mill scale can be reduced by suitable reductant to produce DRI (Direct reduced iron) or metallized iron ore. During the direct reduction process mill scale or iron ore has been reduced in a solidstate at a high temperature below the melting point (T < 1300 °C) in the presence of suitable reductants (solid or gaseous) to give metallized iron ore or DRI.

Much of the remaining iron ore resources in Brazil consist of lowgrade itabirite ores. Accordingly, a typical beneficiation circuit includes a fourstaged crushing/screening plant, followed by grinding in a closedcircuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.
