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)
The book was greatly influential, and for more than a century after it was published, De Re Metallica remained a standard treatise used throughout Europe. The German mining technology it portrayed was acknowledged as the most advanced at the time, and the metallic wealth produced in German mining districts was the envy of many other European ...
The titanium produced by the Hunter process is in the form of powder called sponge fines. This form is useful as a raw material in powder metallurgy. The main limiting factor for the usefulness of the Hunter process is the difficulty of separating the produced NaCl from the titanium. The vapor pressure of NaCl produced in the Hunter process is ...
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 ...
Von Stahel und Eysen (English: On Steel and Iron) is the first printed book on metallurgy, published in 1532 by several publishers: Kunegunde Hergot in Nuremberg, Melchior Sachs in Erfurt, and Peter Jordan in Mainz. It has been suggested that Hergot was probably the first to publish the text, as the material seems to come from Nuremberg: its ...
It allows to process metals at moderate temperatures in a non-aqueous environment which allows controlling metal speciation, tolerates impurities and at the same time exhibits suitable solubilities and current efficiencies. This simplify conventional processing routes and allows a substantial reduction in the size of a metal processing plant.

Metals have become so central to cellular function that the collection of metal-binding proteins (referred to as the metallomes) accounts for over 30% of all proteins in the cell. Metals are known to be involved in over 40% of enzymatic reactions, and metal-binding proteins carry out at least one step in almost all biological pathways. [1]
