Общемировое потребление TiO2 составляет 7 – 7,5 млн т ежегодно. Диоксид титана в основном получают из ильменитовых и рутиловых концентратов. К наиболее крупным производителям относятся Китай, США, Германия, Великобритания, Мексика, Саудовская Аравия. Помимо природных ресурсов титана существуют техногенные источники. К такому типу ресурсов относятся титансодержащие шлаки, получаемые в результате пирометаллургической переработки руд и концентратов, содержащих диоксид титана. Данные шлаки, помимо диоксида титана, содержат кремний в форме диоксида, силикатов или алюмосиликатов, химическая переработка которых затруднена ввиду их высокой температуры плавления (более 2000 °С) и химической устойчивости данных соединений в минеральных кислотах (серная, азотная, соляная). Переработка такого сырья осуществляется «классическими» хлорным и сернокислотным способами. Фториды в промышленности используются при получении соединений алюминия, циркония, урана, бериллия, ниобия и т. д., что свидетельствует о возможности применения фторидных способов для переработки и титановых шлаков. В статье рассматривается метод получения диоксида титана, основанный на использовании гидродифторида аммония NH4HF2 , обладающего высокой реакционной способностью к ряду химически стойких оксидов (оксиды кремния, титана, алюминия и т.д.). Фтораммонийный способ переработки титанового шлака с применением NH4HF2 включает в себя разложение шлака в расплаве NH4HF2 с последующей возгонкой примеси кремния. Очистка от примесей железа, алюминия и др. осуществляется с использованием раствора NH4HF2 . Дальнейшее осаждение титана с обработкой осадка растворами AlCl3 и ZnCl2 с последующей кальцинацией позволяет получить рутильную модификацию диоксида титана.</p></abstract><trans-abstract xml:lang="en"><p>Titanium dioxide is the most common titanium-containing product on the world market, and the demand for it is increasing. The global consumption of TiO2 is 7 – 7.5 million tons annually. Titanium dioxide is mainly obtained from ilmenite and rutile concentrates. The largest producers are China, USA, Germany, UK, Mexico, and Saudi Arabia. In addition to the natural resources of titan, there are man-made sources. This type of resource includes titanium-containing slags obtained as a result of pyrometallurgical processing of ores and concentrates containing titanium dioxide. These slags, in addition to titanium dioxide, contain silicon in the form of dioxide, silicates or aluminosilicates, whose chemical processing is difficult due to their high melting point (more than 2000 °C) and the chemical stability of these compounds in mineral acids (sulfuric, nitric, hydrochloric). Processing of such raw materials is carried out by “classical” chlorine and sulfuric acid methods. The use of fluorides in industry is realized in the production of aluminum, zirconium, uranium, beryllium, niobium, etc., which indicates the possibility of using fluoride methods for titanium slags processing. The article discusses a method for producing titanium dioxide based on the use of ammonium hydrodifluoride NH4HF2 , which has a high reactivity to a number of chemically resistant oxides (oxides of silicon, titanium, aluminum, etc.). The fluoroammonium method for processing titanium slag using NH4HF2 involves slag decomposition of in NH4HF2 melt followed by silicon admixture sublimation. Cleaning from iron, aluminum and other impurities is carried out using a solution of NH4HF2. Further precipitation of titanium with treatment of the precipitate by AlCl3 and ZnCl2 solutions followed by calcination allows to obtain a rutile modification of titanium dioxide.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диоксид титана</kwd><kwd>титановый шлак</kwd><kwd>гидродифторид аммония</kwd><kwd>рутил</kwd><kwd>анатаз</kwd><kwd>пигмент</kwd><kwd>фтораммонийное разложение</kwd><kwd>гидрометаллургия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium dioxide</kwd><kwd>titanium slag</kwd><kwd>ammonium bifluoride</kwd><kwd>rutile</kwd><kwd>anatase</kwd><kwd>pigment</kwd><kwd>fluoroammonium decomposition</kwd><kwd>hydrometallurgy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках программы повышения конкурентоспособности Томского политехнического университета и при финансовой поддержке РФФИ (проект № 19-35-50074 мол_нр).</funding-statement><funding-statement xml:lang="en">The work was performed within the framework of the program for increasing the competitiveness of the Tomsk Polytechnic University and with financial support of the Russian Foundation for Basic Research (project No. 19-35-50074 mol_nr).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bernhardt D., Reilly J.F.
