    Reduction mechanism of titanomagnetite concentrate by carbon monoxide by Sun H.Y., Dong X.J., She X.F., Xue Q.G., Wang J.S.

    Published 2013-01-01
    “…Above 1123 K, the reduction is controlled by interfacial chemical reaction at early stage of the reaction and then turns to the internal diffusion controlling with reaction processing. The reduction path at temperatures above 1123 K is suggested as follow: Fe3-xTixO4 → (x+y-1)FeO + Fe4-2x-yTixO4-y → (x+y-1)Fe + Fe4-2x-yTixO4-y → (3-x)Fe + xTiO2 (0<y<4-2x, x=0.27±0.02)…”
