The process is set up to obtain the chemical components and properties most suitable for the next metal extraction or enrichment, which includes mineral processing, calcination, roasting, …

An International Journal devoted to all aspects of the Aqueous Processing of Metals Hydrometallurgy aims to compile studies on novel processes, process design, chemistry, modelling, control, economics and interfaces between unit operations, and to provide a forum for discussions on case histories and operational difficulties. Topics covered …

Hydrometallurgy refers to the extraction of metals and production of inorganic substances from minerals through aqueous solutions. Although the entire amount of iron, lead, tin, and antimony and major production of copper and nickel come from the pyrometallurgical route, hydrometallurgy plays an important role in the extraction of …

Special Issue Information. Dear Colleagues, Hydrometallurgy, which involves the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual …

Canadian Metallurgical Quarterly publishes original contributions on all aspects of metallurgy and materials science, including mineral processing, hydrometallurgy, pyrometallurgy, materials processing, physical metallurgy and the service behaviour of materials. An invaluable resource for international researchers and …

Hydrometallurgy, usually called the leaching process, is a process of extracting metal ions from the mineral resources, both primary and secondary resources, using a solvent [13]. This process is ...

This Special Issue of Metals is focused on the recycling of metals using mineral processing, hydrometallurgy, electrometallurgy, and pyrometallurgy. The source of the metals may be recycled ...

Chemical mineral processing is closely related to pyrometallurgy and hydrometallurgy. It uses the differences in chemical properties between minerals and uses the ... or after the chemical mineral processing. When chemical mineral processing is adopted, a closed-circuit circulation process will be adopted as far as possible to …

Pyrometallurgy and hydrometallurgy are the two main processes to recover valuable metals from ore and secondary resources. While pyrometallurgy uses high temperatures to extract metals, in …

Hydrometallurgy involves the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual …
