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 pyrometallurgical process of a water jacket furnace, when smelting copper sulphide ores, was fundamentally different to a conventional blast furnace used to make iron, or a water jacket furnace used to make lead.
The basic objective of steeluniversity.org is to inform university students and their teachers about steel technologies and to attract young people to the global steel industry. Another major aim is to reduce the cost of in-service training at steel companies by providing them with freely available training and professional development material.
Physical metallurgy is one of the two main branches of the scientific approach to metallurgy, which considers in a systematic way the physical properties of metals and alloys. It is basically the fundamentals and applications of the theory of phase transformations in metal and alloys. [ 1 ]

A bladesmith from Damascus, c. 1900 A metalsmith or simply smith is a craftsperson fashioning useful items (for example, tools, kitchenware, tableware, jewelry, armor and weapons) out of various metals. [1]
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within the ore, into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings.
In metallurgy, Keller's reagent is a mixture of nitric acid, hydrochloric acid, and hydrofluoric acid, used to etch aluminum alloys to reveal their grain boundaries and orientations. [1] It is also sometimes called Dix–Keller reagent , after E. H. Dix, Jr., and Fred Keller of the Aluminum Corporation of America , who pioneered the use of this ...
