BENEFICIATION OF ILMENITE ORES - LAPORTE

We claim 1. A process for beneficiating a weathered ilmenite ore, which comprises forming from the ilmenite under non-oxidizing conditions and without reducing more than 1/15 by weight of the iron content of the ilmenite, a material of which at least 20% by weight comprises pseudobrookite, reducing the said material to yield a material having at least 4% of its iron content (calculated

Beneficiation of ilmenite to rutile by selective ...

1986-1-1 · However, the raw material in this process has to be a high titania-containing material such as rutile, which is rarer and costlier than ilmenite. Consequently greater emphasis is being laid on developing a process for physical and or chemical beneficiation of natural ilmenite to a synthetic rutile containing more than 90% titanium dioxide.
