  2. 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 .

  3. Hydrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Hydrometallurgy

    Metal recovery is the final step in a hydrometallurgical process, in which metals suitable for sale as raw materials are produced. Sometimes, however, further refining is needed to produce ultra-high purity metals. The main types of metal recovery processes are electrolysis, gaseous reduction, and precipitation.

    Surface gold mine with haul truck in foreground, in Kalgoorlie, Australia. Mining in the engineering discipline is the extraction of minerals from the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying.

    en.wikipedia.org/wiki/Outline_of_mining

    Underground mining (soft rock) There are three directions by which an underground mine may be conducted: Drift mining, mining horizontally; Shaft mining, mining vertically; Slope mining, mining at an inclined angle Stoping is the process of extracting out the ore from underground, leaving a hole called a stope; Room and pillar; Longwall mining ...

  7. Underground hard-rock mining - Wikipedia

    en.wikipedia.org/wiki/Underground_hard-rock_mining

    There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material (muck out round), scaling (removing any unstable slabs of rock hanging from the roof and ...

  8. Heap leaching - Wikipedia

    en.wikipedia.org/wiki/Heap_leaching

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials.

  9. Extractive metallurgy - Wikipedia

    en.wikipedia.org/wiki/Extractive_metallurgy

    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 ...
