Abstract
Традиционный способ извлечения молибдена из концентратов и обожжённых концентратов заключается в гидрометаллургическом и пирометаллургическом переделах. При этом гидрометаллургический передел является многостадийным, так как необходимо очистить растворы от большого количества вредных примесей. При этом чистота металлического молибдена составляет 99,0-99,8%. Для увеличения степени чистоты применяются дополнительные переделы, которые значительно повышают стоимость конечного продукта и уменьшают степень извлечения. Максимально достигнутая чистота составляет 99,95 вес.%. Целью представленного изобретения является разработка процесса получения высокочистого молибдена (до 99,995 вес.%) одностадийным процессом низкотемпературного хлорирования диоксида молибдена (МоО), полученного из молибденового обожжённого концентрата. Процесс низкотемпературного хлорирования при температуре 190-200°С является высокоселективным способом извлечения молибдена из технического сырья, одновременно повышается степень извлечения. Низкая температура процесса позволяет изготовить аппаратуру из недорогих конструкционных нержавеющих сталей.The traditional method of extracting molybdenum from concentrates and calcined concentrates is hydrometallurgical and pyrometallurgical processing. In this case, the hydrometallurgical processing is a multistage process, since it is necessary to purify the solutions from a large amount of harmful impurities. At the same time, the purity of metallic molybdenum is 99.0-99.8%. To increase the degree of purity apply additional redistribution, which significantly increases the cost of the final product and reduce the degree of extraction. The maximum achieved purity is 99.95 wt.%. The aim of the present invention is to develop a process for the production of high-purity molybdenum (up to 99.995 wt.%) By a single-stage process of low-temperature chlorination of molybdenum dioxide (MoO) obtained from molybdenum calcined concentrate. The process of low-temperature chlorination at a temperature of 190-200 ° C is a highly selective method for extracting molybdenum from technical raw materials, while the degree of extraction increases. The low temperature of the process makes it possible to manufacture equipment from inexpensive structural stainless steels.
