Recovery Of The Recovery Zinc Concentrate In A Weakly Reducing Gas Atmospheric Environment, B T. Berdiyarov, S T. Matkarimov, J B. Ismailov
Technical science and innovation
This article provides information on the formation of substances resulting from the roasting of sulfide-zinc concentrates, which negatively affects the course of subsequent stages. The resulting calcine was sent for reduction roasting in a weakly reducing inert gas atmosphere. Based on this, it can be assumed that the impact on the calcine of "weak" energetic inert gases the reduce minimises or formation of ferrites and zinc silicates. Since the principal primary using agent is gaseous H2, (hydrogen) in a mixture of gases with a weak reducing environment, all redox reactions occurring in total reduction were studied. The course …

Hydrometallurgy Over The Years (Geçmişten Günümüze Hidrometalurji), Fathi Habashi

Binlerce yıl önce insanlar, nasıl fırın yapacaklarını, ayaçları eritmek için ateşi nasıl kullanacaklarını ve metalleri nasıl üreteceklerini öğrenmelerine rağmen, cevherlerin zenginleştirilmesinde çözeltilerin kullanımı, asit ve bazların öğrenilip kullanıldığı simyacılar dönemine rastlamaktadır. Bununla birlikte modern hidrometalurjinin başlangıcı, iki önemli prosesin keşfedildiği 19. yüzyılın sonlarına dayandırılabilir. Bu prosesler, altın ve gümüşün çözündürülmesi için siyanür liç prosesi ve boksit cevherlerinin değerlendirilmesi için geliştirilen Bayer prosesidir. Daha sonra, 1940’larda, uranyum zenginleştirilmesi ile ilgili olarak Manhattan Projesi (ABD) bir dönüm noktası olmuştur. O tarihten itibaren, hidrometalurji giderek ilerlemekte ve hatta bazı pirometalurjik proseslerin yerinialmaktadır. Bu süreçte Kanada’nın, özellikle uranyum, nikel, kobalt ve çinko kazanımı ile …

Thousands of years ago people had learned how to build furnaces and use fire to melt rocks and produce metals but the use of aqueous solutions for ore processing came much later, mainly at the time of the alchemists when acids and alkalies became known and used. Modern hydrometallurgy, however, can be traced back to the end of the 19th century when two major operations were discovered: the cyanidation process for gold and silver extraction and the Bayer process for bauxite treatment. Later, in the 1940s, a breakthrough came during the Manhattan Project in USA in connection with uranium extraction. …
