ABSTRACT OF THE DISCLOSURE: The process basically consists of the removal of the impurities contained in the titanium minerals, in which it appears in the form of oxides, which cannot be eliminated by the conventional hydro-metallurgical processes. The conditioning of the mineral by pire-metallurgical treatment followed by mag- netic separation, removes a part of the magnetic impurities at the same time that it exposes those impurities to the action of the leaching acids and thus makes it possible for them to be removed easily. The alkaline treatment following the acid leach- ing permits elimination of the phosphores 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 obtaining of pigments and metallic titanium, which are the main forms in which titanium ores enter into consumption.
