The Bond Work Index for oolitic iron ore reported by Bond was 11.33 KWh/short ton (Bond, 1953). A subsequent article by Manieh (1986) took the product from milling the Wadi Fatima oolitic iron ore as described above and noted that the ground oolites were nearly covered by adhering gangue fines.

Australian mining firm Rio Tinto has increased spot sales of its 59pc Fe SP10 iron ore fines, as Chinese steel mills seek out lower cost feedstocks to counter narrowing profit margins. Rio Tinto rarely offers its supplementary product (SP) 10 into Chinese spot markets where buyers have resisted paying full value for sub-60pc Fe fines on a $/dry ...

To preserve the iron ore, secondary sources like ore fines, mill scale, slime and low grade iron ore (after beneficiation) can be utilized. These shall not only improve the reserves position, to the tune of about 10-15%, by extracting metal is of vital concern for resource conservation and pollution control.
