    used as feedstock for eAF steel production. Two iron oxides—hematite (Fe 2 o 3) and magnetite (Fe 3 o 4)— are the primary ore minerals of iron found in the United States. The principal form of iron ore mined in the United States contains hematite and magnetite in varying proportions, averaging 25% to 30% Fe, and occurs in hard, finegrained,

    According to the shrinking unreacted core model, the reduction of hematite (Fe 2 O 3) to magnetite (Fe 3 O 4) proceeded from the outer surface to the center of the hematite ore particle. The product layer (magnetite layer) thickened with the progression of reduction, and the unreacted gangue in the hematite ore particle was inevitably encapsulated by the newgeneration magnetite (Fe 3 O 4 ).

    Alpha hematite is the common form of Fe203 crystallizing in the rhombohedral system and will hereafter be referred to as hema­ tite. Gamma hematite has the same cubic crystal structure as magne­ tite, Fe304* but has the chemical composition Fe203. It is dis­ tinctly ferromagnetic but somewhat unstable. 9 .
