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 ...
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. [ 1 ] [ 2 ] [ 3 ] Metals like zinc , copper , lead , aluminium as well as rare and noble metals are of particular interest in this field, [ 1 ] while the more ...
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]
Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling .
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials.
A Kaldo converter (using the Kaldo process or Stora-Kaldo process) is a rotary vessel oxygen based metal refining method.Originally applied to the refining of iron into steel, with most installations in the 1960s, the process is (2014) used primarily to refine non ferrous metals, typically copper.
The paper is well-illustrated, and covers metal and ore mining and extractive metallurgy (and some popular science), focusing primarily on the United States, Canada, and Mexico, and to a lesser extent Central and South America, Australia, New Zealand, and South Africa, with scattered articles on mining around the world (e.g. Russia, Korea).
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 ...
