Bhadeshia has developed a wide range of freely accessible teaching materials on metallurgy and associated subjects. [31] The subject matters cover crystallography, metals and alloys, steels in particular, phase transformation theory, thermodynamics, kinetics, mathematical modelling in materials science, information theory, process modelling, thermal analysis, ethics and natural philosophy.
De re metallica (Latin for On the Nature of Metals [Minerals]) is a book in Latin cataloguing the state of the art of mining, refining, and smelting metals, published a year posthumously in 1556 due to a delay in preparing woodcuts for the text.
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 ...
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt , [ 1 ] were made from meteoritic iron-nickel . [ 2 ]
A treatise is a formal and systematic written discourse on some subject concerned with investigating or exposing the principles of the subject and its conclusions. [1] A monograph is a treatise on a specialized topic.
The 16th-century process of separating copper and silver using liquation, described by Georg Agricola in his 1556 treatise De re metallica, [1] remained almost unchanged until the 19th century when it was replaced by cheaper and more efficient processes such as sulphatization and eventually electrolytic methods.
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 .
Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting) to produce blister copper. [1] The matte may also collect some valuable minor constituents such as noble metals, minor base metals, selenium or tellurium.
