Abstract

The invention provides a mineral recovery process (10) which allows the processing of an ore (12) in order to separate iron (14), titanium (16), silica (18) and vanadium (20) from the ore which mineral recovery process includes the steps of : (a) producing a gaseous reductant (24); (b) treating the ore by way of direct reduction (22) with the gaseous reductant to produce a first product (36); and (c) separating the iron from the first product by way of a pyro-metallurgical process followed by the separation of the titanium, silica and vanadium from the first product by way of a hydro-metallurgical process.
