Study on Reduction Behavior of Vanadic Titanomagnetite mixed Coal

The both experiments of DSC-TG of vanadic titanomagnetite bearing coal and reduction of the VTMCM pellet in electric furnace were carried out in order to understand the reduction behavior of vanadic titanomagnetite. The results are found that the absorbing heat is very high and reduction products have not only simple phase but also complex solid solutions in the reduction process of vanadic titanomagnetite. It shows that the process is very complex, simple iron oxide and complex iron ones are reduced step-by-step in parallel, the reduction sequence of simple iron oxides and complex ones are Fe2O3, Fe3O4, FeO and Fe2TiO5, FeTiO3, Fe2TiO4, FeTi2O5, respectively and the required temperature in which iron oxides can well be reduced should be higher than 1300 degrees C.
