Abstract: The process basically consists of the removal of the impurities contained in titanium minerals, in which titanium is present in the form of oxides in complex association with other minerals which cannot be eliminated by the conventional hydro-metallurgical processes.The conditioning of the mineral by pyro-metallurgical treatment followed by magnetic separation, removes a part of the magnetic impurities at the same time that it exposes those impurities to the action of leaching acids and thus makes it possible for them to be removed easily. The alkaline treatment following the acid leaching permits elimination of the phosphorus contained as a harmful impurity, and makes it possible to secure a product within the specifications of the consumer market for use as a raw material mainly for the obtention of pigments and metallic titanium, which are the main forms in which titanium ores enter into consumption.
