  2. Volcanogenic massive sulfide ore deposit - Wikipedia

    en.wikipedia.org/wiki/Volcanogenic_massive...

    Volcanogenic massive sulfide deposits are forming today on the seafloor around undersea volcanoes along many mid ocean ridges, and within back-arc basins and forearc rifts. Mineral exploration companies are exploring for seafloor massive sulfide deposits ; however, most exploration is concentrated in the search for land-based equivalents of ...

  3. Sedimentary exhalative deposits - Wikipedia

    en.wikipedia.org/.../Sedimentary_exhalative_deposits

    In an ideal exhalative model, hot dense brines flow to depressed areas of the ocean topography where they mix with cooler, less dense, sea water, causing the dissolved metal and sulfur in the brine to precipitate from solution as a solid metal sulfide ore, deposited as layers of sulfide sediment. [1]

  4. Seafloor massive sulfide deposits - Wikipedia

    en.wikipedia.org/wiki/Seafloor_massive_sulfide...

    Mineral associations may vary (1) in different mineralized structures, either syngenetic (namely, passive precipitation in chimneys, mounds and stratiform deposits) or epigenetic (structures that correspond to feeder channels, and replacements of host rocks or pre-existing massive sulfide bodies), or structural zonation, (2) from proximal to ...

  5. Seabed mining - Wikipedia

    en.wikipedia.org/wiki/Seabed_mining

    Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.

  6. Sulfide mineral - Wikipedia

    en.wikipedia.org/wiki/Sulfide_mineral

    Some sulfide minerals are economically important as metal ores. The sulphide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulpharsenides and the sulphosalts. [1] [2] Sulphide minerals are inorganic compounds. Pyrite

  7. Ore - Wikipedia

    en.wikipedia.org/wiki/Ore

    Magmatic Sulfide Deposits form from mantle melts which rise upwards, and gain sulfur through interaction with the crust. This causes the sulfide minerals present to be immiscible, precipitating out when the melt crystallizes. [16] [17] Magmatic sulfide deposits can be subdivided into two groups by their dominant ore element:

  9. Ore genesis - Wikipedia

    en.wikipedia.org/wiki/Ore_genesis

    The best nickel deposits are formed where sulfide accumulates in the base of lava tubes or volcanic flows — especially komatiite lavas. Komatiitic nickel-copper sulfide deposits are considered to be formed by a mixture of sulfide segregation, immiscibility, and thermal erosion of sulfidic sediments.
