The conventional blast furnace process produces molten metal by reducing the ore, and separating out the silica as slag. Water jacket furnaces, when smelting sulphide copper ores, used an oxidation reaction that produces molten copper matte , which must be further treated in a convertor (similar in concept to a Bessemer convertor ) or ...

This bimonthly section is uniquely focused on process metallurgy and materials processing science. Coverage emphasizes the theoretical and engineering aspects of the processing of metals and other materials, including studies of electro- and physical chemistry, mass transport, modeling, and related computer applications.
Metallurgy derives from the Ancient Greek μεταλλουργός, metallourgós, "worker in metal", from μέταλλον, métallon, "mine, metal" + ἔργον, érgon, "work" The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense in the 1797 Encyclopædia ...

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, [1] to extract and purify nickel. The process was used commercially before the end of the 19th century, [ 2 ] and particularly by the International Nickel Company in the Sudbury Basin . [ 3 ]
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials.
As of 2000, the waelz process is considered to be a "best available technology" for flue dust zinc recovery and the process is used at industrial scale worldwide. [7] As of 2014, the Waelz process is the preferred or most widely used process for zinc recovery of zinc from electric arc furnace dust (90%). [8]
