Magnetite Oxide is one of the major ores of iron, and the most magnetic of all the naturally occurring minerals in nature. Its primary use is as a source of iron. Magnetite, which has the International Union of Pure and Applied Chemistry (IUPAC) name iron (ii,iii) oxide, it is a metallic, black, opaque mineral that has the chemical formula Fe 3 ...

It is suggested that oxygen enrichment in the gas atmosphere, during continuous heating of magnetite pellets, can cause pellets to be oxidized throughout their volumes, eliminating unoxidized cores. The peculiarities of the oxidation kinetics of magnetite concentrate imply that such oxygen enrichment might be particularly effective …
