Relevance. The demand for high-grade titanium dioxide concentrates with a content of TiO₂ at least 80%. The limited reserves of such raw materials affect the prices as well. These concentrates are used in the production of metallic titanium (powder, sponge) and its alloys, as well as for the production of pigment titanium dioxide, welding electrodes, etc. Due to the limited reserves, these concentrates are obtained from concentrates of other more common titanium minerals – ilmenite, leucoxene. Due to the presence of limiting impurities in the above-mentioned minerals, there is a need to develop a method for processing them in order to bring the resulting product to the requirements of industrial. Aim. To review the existing methods of chemical enrichment of titanium concentrates to obtain a concentrate of synthetic rutile or its analogues, allowing them to be used in similar applications. Methods. Search and analysis of existing studies on this issue. The elemental and mineralogical composition of the rutile-leucoxene concentrate of the Tuganskoe deposit was also determined using elemental and X-ray diffraction analysis. Results and conclusions. It was found that the considered titanium minerals contained in the concentrates can be processed using both classical and other methods that have not yet found wide application in industry. It is worth highlighting the ilmenite concentrate, which can be used both to obtain titanium sponge and pigment titanium dioxide. The rutile-leucoxene concentrate of the Tuganskoe deposit, which is a mixture of titanium minerals (rutile, pseudorutile, sphene, anatase, brookite, ilmenite) and other minerals (zircon, quartz, etc.), can be considered as an unconventional titanium-containing raw material. Its processing is limited due to the large number of impurities. Their removal will require various options for chemical enrichment. A potential solution to the problem of its processing is the use of ammonium fluorides, which react with the vast majority of chemically resistant oxides under relatively mild conditions.
