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.
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 ]
Carl Josef Bayer (also Karl Bayer, 4 March 1847 – 4 October 1904) was a chemist from Austria-Hungary who invented the Bayer process of extracting alumina from bauxite, essential to this day to the economical production of aluminium.
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.
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 .
Georgius Agricola (1494–1555) presented details of lead smelting methods and facilities current in Europe in the first half of the 16th century in Book IX of his treatise on mining and metallurgy, De Re Metallica. Methods ranged from primitive open-hearth arrangements (essentially bonfires on which lead ore was piled) to blast furnaces ...
Georgius Agricola (/ ə ˈ ɡ r ɪ k ə l ə /; born Georg Bauer; 24 March 1494 – 21 November 1555) was a German Humanist scholar, mineralogist and metallurgist.Born in the small town of Glauchau, in the Electorate of Saxony of the Holy Roman Empire, he was broadly educated, but took a particular interest in the mining and refining of metals.
This process was used from Lydian to post-medieval times. It is a solid state process relying on common salt as the active ingredient but it is possible to use a mixture of saltpetre (KNO 3) and green vitriol (FeSO 4). The basic process involved the mixing of argentiferous gold foil (in later periods granules were used), common salt and brick ...
