ABSTRACT:
The present invention provides a method for recovering vanadium, niobium, tantalum and zirconium from vanadiferous residues arising from the chlorination of titaniferous ores. Such residues contain chlorides of these metals and/or titanium, aluminum, iron, chromium and manganese together with carbon and unreacted titaniferous ore. The method comprises first moistening these residues with water and then treating them with hot water for a sufficient period of time to extract substantially all the vanadium into solution which is separated from insoluble material comprising carbon and unreacted titaniferous ore together with substantially all the niobium, tantalum and zirconium.
