Использование: гидрометаллургия осмия, получение осмиевого концентрата при извлечении осмия из кислых растворов, в частности из ренийсодержащей промывной серной кислоты. Сущность способа: концентрируют осмий в экстрагенте при одновременном экстрационном извлечении рения техническим триалкиламином. Экстракт, содержащий рений и осмий, нагревают до 50-80°С с выдержкой в течение 20-30 мин. Охлаждают его. После реэкстрации рения регенерированный экстрагент направляют на экстракцию.Usage: osmium hydrometallurgy, obtaining osmium concentrate when extracting osmium from acidic solutions, in particular from rhenium-containing washing sulfuric acid. The essence of the method: concentrate osmium in the extractant while extracting the extraction of rhenium technical trialkylamine. The extract containing rhenium and osmium is heated to 50-80 ° C with a holding time of 20-30 minutes. Cool it down. After reextraction of rhenium, the regenerated extractant is sent for extraction.
