A Treatise on Metallurgy, including vol. i. On Fuel, Copper, Zinc, and Brass; vol. ii. On Iron and Steel, 1864, 2nd edition 1875; vol. iii. On Lead, 1870; and vol. iv. On Silver and Gold, 1880. His 1851 survey resulted were embodied in the volume on Iron and Steel. This treatise was the first work of its kind written in modern times.
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.
Biohydrometallurgy is a technique in the world of metallurgy that utilizes biological agents (bacteria) to recover and treat metals such as copper. Modern biohydrometallurgy advances started with the bioleaching of copper more efficiently in the 1950s [ 1 ]
Metal recovery is the final step in a hydrometallurgical process, in which metals suitable for sale as raw materials are produced. Sometimes, however, further refining is needed to produce ultra-high purity metals. The main types of metal recovery processes are electrolysis, gaseous reduction, and precipitation.
16th century cupellation furnaces (per Agricola). Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore.
Pyrometallurgy is a branch of extractive metallurgy.It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. [1]

Argonoxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminium. After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization , reduction , and desulfurization .
