ABSTRACT:
The invention relates to the beneficiation of both natural and artificial titaniferous ores, specifically ilmenites by adding to the ores a fluoride, preferably a normally insoluble fluoride in an amount such that the percentage of fluorine ion relative to the titania values lies between 13% and 50%, adding to the mixture hydrochloric acid, the fluorine ions acting as an activating agent. After dissolution, the titanium is precipitated out, as a mixture of titanium dioxide, titanium oxy hydroxy fluoride and titanium oxy fluoride, the iron values largely remaining in solution.
