Disclosed herein are compositions and methods of making a hard magnetic material from iron oxide fines, the hard magnetic material having a general formula MFeO. In one aspect, the method comprises a) providing an iron oxide fine; b) providing a metal carbonate of a general formula M(CO); c) mixing the iron oxide fine and the metal carbonate to form a mixture; d) calcining the mixture of the iron oxide fine and the metal carbonate; wherein M is a divalent metal ion.

Hard magnetic compositions from iron oxide fines and methods for making same

The present invention relates to a process for the recycling of steel industry iron bearing by-products into a shape suitable for feeding into a direct reduction furnace, comprising the steps of mixing and grinding 50 to 99 wt % of ore and pellet fines and 1 to 50 wt % of slurry, mill scale and/or bag house dust, pelletizing the mixture and indurating the pellets so obtained by heating for 5-60 minutes at a temperature in the range of 1100-1350&#xb0; C.; and a pellet produced from Iron bearing waste material and having compression strength of at least 2.8 kN and/or a drop number of at least 3.
