A METALLURGICAL PROCESS FOR UPGRADING FERRO-TITANIFEROUS MINERAL CONCENTRATE USING TIME DEPENDENT MAGNETIC FIELDS

摘要

There is provided a metallurgic process for upgrading ferro-titaniferous mineral concentrate (comprising more than 10% by weight of iron content calculated as FeO) using time dependent magnetic fields. The process comprises reducing a substantial portion of the iron content at temperature below the flow point of the titaniferous phase of the mineral concentrate in the presence of a time dependent magnetic field, wherein the time dependent magnetic field is used to at least contribute to the reduced iron content coalescing into iron spheroids and subsequently physically separating the iron spheroids.
