Способ извлечения металлов из отходов титанового производства относится к цветной металлургии и может быть использован при переработке, утилизации и обезвреживании отходов получения тетрахлорида титана. Цель изобретения - упрощение технологии обеспечения условий создания малоотходной технологии обезвреживания отходов и утилизации ценных компонентов в форме товарных продуктов и/или полупродуктов. Для этого отработанный расплав титановых хлораторов выщелачивают в воде, осаждают из раствора хром, редкие и радиоактивные металлы щелочным реагентом, отделяют хлоридный раствор от осадка гидроксидов металлов, осадок обрабатывают щелочным раствором гипохлорита натрия, фильтруют пульпу, отделяя редкометальный концентрат хроматного раствора. Затем хроматный и хлоридный растворы смешивают в соотношении 1:1-2 и обрабатывают щелочным реагентом до pН 6 - 9.The method of extracting metals from titanium production wastes relates to non-ferrous metallurgy and can be used in the processing, utilization and neutralization of wastes for the production of titanium tetrachloride. The purpose of the invention is the simplification of the technology to ensure the creation of low-waste technology for waste disposal and disposal of valuable components in the form of commercial products and / or intermediates. For this, the spent melt of titanium chlorinators is leached in water, chromium is precipitated from the solution, rare and radioactive metals with an alkaline reagent, the chloride solution is separated from the metal hydroxide precipitate, the precipitate is treated with an alkaline sodium hypochlorite solution, the pulp is filtered, and the rare metal concentrate of the chromate solution is filtered. Then the chromate and chloride solutions are mixed in a ratio of 1: 1-2 and treated with an alkaline reagent to pH 6 - 9.
