Abstract
Изобретение относится к неорганической химии и химической технологии, а именно к редкометальной металлургии, конкретнее к извлечению и очистке вольфрамовых и молибденовых соединений газофазным методом. Целью настоящего изобретения является извлечение вольфрама и молибдена в низкотемпературном режиме хлорирования (НТХ) путем переработки низкосортного сырья поточно-селективным методом. Поставленная цель достигается созданием способа низкотемпературного режима хлорирования (НТХ) бедного рудного сырья для извлечения вольфрама и молибдена и устройства для его осуществления с установкой системы раздельной конденсации возгонов с обеспечением непрерывности ее функционирования и дальнейшего совершенного разделения твердофазных конденсатов в виде индивидуальных продуктов. Установка состоит из гранулятора шихты (1), контейнеров (2), сушильной камеры (3) горячим воздухом, затем контейнеры сверху тельфером (7) при помощи подъемника контейнеров (8) погружаются в реактор (6), в который пропускается хлористая сера (4), полученная ранее пропусканием хлора через жидкую серу (5). В конденсаторе (9) конденсируется основная доля паров хлорного железа; в конденсаторе (11) конденсируется основная масса паров оксотетрахлорида вольфрама; в конденсаторе (13) конденсируется молибден, если он присутствует в вольфрамовом рудном сырье, что бывает нередко. Из конденсатора (13) выходит сернистый газ с микропримесью паров хлоридов титана, рения, мышьяка и других возможных элементов. Для отделения этих примесей сернистый газ проходит через промывную башню (14), орошаемую оборотной водой, подаваемой насосом (15); очищенный от примесей сернистый газ из промывной башниThe invention relates to inorganic chemistry and chemical technology, namely, rare-metal metallurgy, more specifically to the extraction and purification of tungsten and molybdenum compounds by the gas-phase method. The aim of the present invention is the extraction of tungsten and molybdenum in the low-temperature chlorination mode (STC) by processing low-grade raw materials by the flow-selective method. This goal is achieved by creating a method of low-temperature chlorination (NTX) mode of poor ore raw materials for the extraction of tungsten and molybdenum and a device for its implementation with the installation of a separate sublimation condensation system ensuring continuity of its operation and further perfect separation of solid-phase condensates in the form of individual products. The installation consists of a granulator charge (1), containers (2), a drying chamber (3) with hot air, then the containers on top of the hoist (7) with the help of a container lift (8) are immersed in a reactor (6), into which sulfuric chloride (4 , previously obtained by passing chlorine through liquid sulfur (5). In the condenser (9) the main fraction of ferric chloride vapor is condensed; in the condenser (11) the bulk of the tungsten oxotetrachloride vapor is condensed; molybdenum is condensed in condenser (13) if it is present in a tungsten ore material, which is not uncommon. Sulfur dioxide escapes from the condenser (13) with a micronutrient vapor of titanium chloride, rhenium, arsenic and other possible elements. To separate these impurities, sulfur dioxide passes through a wash tower (14), irrigated with circulating water supplied by a pump (15); purified sulfur dioxide from the wash tower
