ЧТО ОЗНАЧАЕТ СЛОВО PYROMETALLURGY
Pyrometallurgy
Пирометаллургия является отраслью добывающей металлургии. Он состоит из термической обработки минералов и металлургических руд и концентратов для обеспечения физических и химических превращений в материалах, что позволяет извлекать ценные металлы. Пирометаллургическая обработка может производить товарные продукты, такие как чистые металлы или промежуточные соединения или сплавы, подходящие в качестве сырья для дальнейшей переработки. Примеры элементов, экстрагированных пирометаллургическими процессами, включают оксиды менее реакционноспособных элементов, таких как Fe, Cu, Zn, Chromium, Tin, Manganese. Пирометаллургические процессы обычно сгруппированы в одну или несколько из следующих категорий: ▪ Кальцинирование ▪ Обжарка ▪ Плавка ▪ Очистка Большинство пирометаллургических процессов требуют ввода энергии для поддержания температуры, при которой происходит процесс. Энергия обычно предоставляется в виде сжигания ископаемого топлива, экзотермической реакции материала или электрического тепла. Когда в корме присутствует достаточное количество материала для поддержания температуры процесса исключительно экзотермической реакцией, процесс считается «автогенным». ...

Hydrometallurgy in Extraction Processes
A. GENERAL The difference between pyrometallurgy and hydrometallurgy can
generally be appreciated on the basis of thermodynamic and kinetic
considerations. It is true that thermodynamics is important as the foundation of all
processes.
