  • Iron Ore - Iron Species and Gangue Mineralogy Mapping

    2013-09-16  Automated Hyperspectral Logging. The successful development of iron ore resources is fundamentally linked to our ability to accurately identify not only multiple species of iron oxide minerals, but also sub-species, phases (eg. ochreous vs. hard) and associated gangue minerologies.

  • Gangue - Wikipedia

    OverviewRe-useSee also

    In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals; a worthless rock containing valuable material. The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressi

    In general, phosphorus is considered as a gangue mineral in iron ore because it makes steel brittle. High levels of phosphorus in iron ore attract a penalty and reduces the profit margin substantially[42]. The mineralogy of phosphorus in iron ore depends on the type of iron minerals.

  • Iron processing - Ores Britannica

    Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
