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 exploitation of metals in Aljustrel (mining and metallurgy) began at the end of the 3rd millennium BC, with tartessian mines on the hilltop of Nossa Senhora do Castelo, equidistant from iron deposits in Algares and São João do Deserto. [3] Bronze Age excavations were situated in Mangancha, near faults close to São João. [3]
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
The process was repeated from one pot to the next, the lead accumulating in the pot at one end and metal enriched in silver in the pot at the other. [ 3 ] [ 4 ] The level of enrichment possible is limited by the lead-silver eutectic and typically the process stopped around 600 to 700 ounces per ton (approx. 2%), so further separation is carried ...
The converting process occurs in a converter. Two kinds of converters are widely used: horizontal and vertical. Horizontal converters of the Peirce-Smith type (which are an improvement of the Manhès-David converter ) prevail in the metallurgy of non-ferrous metals. Such a converter is a horizontal barrel lined with refractory material inside.
Metallurgy: A process involving the separating and refining of metals from other substances; [4] Bioleaching: Using biological agents (bacteria) to extract metals or soils; [ 5 ] general term used to encompass all forms biotechnological forms of extraction ( hydrometallurgy , biohydrometallurgy, biomining , etc)
