  2. Biomining - Wikipedia

    en.wikipedia.org/wiki/Biomining

    Biomining techniques only show economic viability as a complementary process to mining, not as a replacement. Biomining may make traditional mining more environmentally and economically friendly, by re-processing fresh or abandoned mine tailings and the detoxification of copper production concentrates to generate economically valuable copper ...

  3. Mineral processing - Wikipedia

    en.wikipedia.org/wiki/Mineral_processing

    Crushing, a form of comminution, one of the unit operations of mineral processing. Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1]

  4. Bioleaching - Wikipedia

    en.wikipedia.org/wiki/Bioleaching

    Bioleaching is the extraction or liberation of metals from their ores through the use of living organisms.Bioleaching is one of several applications within biohydrometallurgy and several methods are used to treat ores or concentrates containing copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

  5. Biohydrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Biohydrometallurgy

    Biohydrometallurgy is used to perform processes involving metals, for example, microbial mining, oil recovery, bioleaching, water-treatment and others. Biohydrometallurgy is mainly used to recover certain metals from sulfide ores.

  6. Solid-phase extraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_extraction

    Solid-phase extraction (SPE) [1] is a solid-liquid extractive technique, by which compounds that are dissolved or suspended in a liquid mixture are separated, isolated or purified, from other compounds in this mixture, according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and ...

  7. Non-ferrous extractive metallurgy - Wikipedia

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

    Copper extraction in particular is of great interest in archeometallurgical studies since it dominated other metals in Mesopotamia from the early Chalcolithic until the mid-to-late sixth century BC. [ 11 ] [ 12 ] There is a lack of consensus among archaeometallurgists on the origin of non-ferrous extractive metallurgy.

  8. Mining - Wikipedia

    en.wikipedia.org/wiki/Mining

    Mining of sulfur from a deposit at the edge of Ijen's crater lake, Indonesia. Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.

  9. Leaching (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(metallurgy)

    Many different techniques in leaching were quickly employed at a large scale. [4] Both synthetic resins and organic solvents were used early on to extract uranium . [ 4 ] Ultimately, the use of organic solvents was less tedious compared to ion exchange through synthetic resins, and further production of uranium and other rare earth metals moved ...
