    en.wikipedia.org/wiki/Non-ferrous_extractive...

    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 ...

  4. Pyrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Pyrometallurgy

    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]

  5. Mineral processing - Wikipedia

    en.wikipedia.org/wiki/Mineral_processing

    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 .

  6. Hydrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Hydrometallurgy

    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.

  7. Kaldo converter - Wikipedia

    en.wikipedia.org/wiki/Kaldo_converter

    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).

  9. Metallurgy - Wikipedia

    en.wikipedia.org/wiki/Metallurgy

    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 ...
