Определены основные технико-экономические показатели производства карбоната лития. Метод хлоридовозгоночного обжига позволяет совместить обжиг руды и возгонку лития с процессом получения (обжигом) портландцементного клинкера. Таким образом появляется возможность распределить энергозатраты высокотемпературного обжига на гораздо больший объем продуктов – клинкер и соли лития. Извлекаемый литий в виде паров хлорида лития улавливается водным поглотительным раствором, имеющим многократно меньший объем по сравнению с объемами выщелачивающих растворов в известковой, сернокислотной или автоклавной щелочной технологиях. Соответственно уменьшаются потоки перерабатываемых растворов, что существенно экономит реактивы и энергию при их переработке, а также значительно снижает капитальные затраты на емкостное оборудование. Благодаря высокому содержанию в литиевых алюмосиликатных рудах оксидов алюминия и кремния возможно их использование в производстве цементного клинкера вместо глинистого компонента шихты.</p></abstract><trans-abstract xml:lang="en"><p>Pilot plant tests were carried out for the technology for chloride sublimation of lithium from petalite ore with concurrent cement clinker production. Main technical and economic indicators of lithium carbonate production were determined. Chloride sublimation roasting allows combining ore roasting and lithium sublimation with the process of Portland cement clinker production (roasting). Thus, it becomes possible to distribute energy expenditure for high-temperature firing over a much larger volume of products – clinker and lithium salts. Lithium recovered in the form of lithium chloride vapors is captured by an aqueous absorption solution, which has a much smaller volume compared to the volumes of leaching solutions in lime, sulfuric acid or autoclave alkaline technologies. Correspondingly, the flows of processed solutions are reduced, which significantly saves reagents and energy during their processing and significantly reduces the capital costs of tank equipment. Due to the high content of aluminum and silicon oxides in lithium aluminosilicate ores, it is possible to use them in the production of cement clinker instead of the clay component of the charge.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>литий</kwd><kwd>петалит</kwd><kwd>хлоридовозгоночный обжиг</kwd><kwd>карбонат лития</kwd><kwd>портландцементный клинкер</kwd><kwd>цемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lithium</kwd><kwd>petalite</kwd><kwd>chloride sublimation roasting</kwd><kwd>lithium carbonate</kwd><kwd>Portland cement clinker</kwd><kwd>cement</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Global electric vehicle market 2020 and forecasts. https://www.canalys.com/newsroom/canalys-global-electricvehicle-sales-2020.</mixed-citation><mixed-citation xml:lang="en">Global electric vehicle market 2020 and forecasts. https://www.canalys.com/newsroom/canalys-global-electricvehicle-sales-2020.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Kudryavtsev P.
