DEVELOPMENT OF NICKEL FERRITES AND METHODS FOR PREPARING SAME USING STEEL INDUSTRY BY-PRODUCT IRON OXIDE FINES
Method for preparing soft cubic ferrites of a general formula MFe2O4 comprising the steps of contacting an iron containing by-product of iron ore processing and a metal oxide of the general formula MxOy, to form a mixture, wherein the stoichiometric ratio of M to iron is in the range from greater than zero to about 2, and wherein M is nickel, magnesium, or zinc, or a combination thereof; and calcining the mixture at a temperature range of from about 1000° C. to about 1500° C. in a static air atmosphere, to form a soft cubic ferrite of a general formula MFe2O4, wherein the mixture is not subjected to an oxidation step or a compacting step prior to calcining.
