Ushbu maqolada reniy metallini ajratib olish, qayta ishlash boyitish usullari haqida umumiy ma’lumot berilib, bugungi kunda reniyning asosiy qo‘llanilishi aviatsiyada gaz turbinalari uchun super qotishmalarda bo‘lib, neftni qayta ishlash katalizatorlarida foydalanish umumiy iste’molning taxminan 10% ni tashkil qiladi. Reniy -1 dan +7 gacha bo‘lgan bir nechta oksidlanish darajasiga ega, eng keng tarqalganlari +7, +6, +5 va +4. U bir oksidlanish holatidan ikkinchisiga osonlik bilan o‘zgaradi, bu jarayon reniy metallini katalizator sifatida ishlatish uchun eng muhim metal hisoblanadi. Ba’zi sulfat kislota va boshqa aralashmalarni o‘z ichiga olgan eritma, erituvchi ekstraktsiyasi yoki qattiq qatlamli ion almashinuvi orqali reniyni qayta tiklashga tayyorlash uchun qayta ishlash haqida ma’lumot berilgan.
В данной статье представлен обзор методов извлечения и переработки металлического рения. Сегодня основное применение рения приходится на суперсплавы для газовых турбин в авиации, а его использование в катализаторах нефтепереработки составляет около 10% от общего потребления. Рений имеет несколько степеней окисления от -1 до +7, наиболее распространенными являются +7, +6, +5 и +4. Он может легко переходить из одной степени окисления в другую, и этот процесс делает металлический рений наиболее важным металлом для использования в качестве катализатора. Сообщается, что раствор, содержащий некоторое количество серной кислоты и других примесей, обрабатывается для подготовки рения для извлечения путем экстракции растворителем или ионного обмена в твердом слое.

This article provides an overview of rhenium metal extraction and processing methods. Today, the main use of rhenium is in superalloys for gas turbines in aviation, and its use in petroleum refining catalysts accounts for about 10% of total consumption. . Rhenium has several oxidation states from -1 to +7, the most common being +7, +6, +5, and +4. It can easily change from one oxidation state to another, a process that makes rhenium metal the most important metal to use as a catalyst. A solution containing some sulfuric acid and other impurities is reported to be processed to prepare rhenium for recovery by solvent extraction or solid-bed ion exchange.
