PROCESS FOR BENEFICIATING MAGNETITE IRON ORE - UNIV.

Magnetite (Fe 3 O 4) (molecular weight 231.55 ) contains 72.36 percent iron. Even if all of the iron appeared as magnetite, no more than about 34.5 to 48.4 percent of the ore would consist of magnetite. Since industrial concentration of this ore is accomplished with magnetic separators, only the iron occurring as magnetite can be recovered.
