  • Photos of gold ores, quartz, telluride gold ore and gold

    This ore shows considerable bright and visible metallic gold disbursed through the quartz vein gold ore. This chunk of vein quartz from Mariposa is typical of gold-quartz material from the mother lode district of California. In most gold ore, the gold is present in tiny specs, either within minerals like pyrite, or spread out free among the quartz. Normally even good, rich gold ore has no gold

  • Gold extraction Wikipedia

    Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

  • Low-Sulfide Quartz Gold Model

    Ore Shoots Control and Distribution of Gold Mineralization Kerrich and Feng (1992) make the point that quartz and quartz-carbonate veins are common in metamorphic belts. The majority of these veins are from a centimeter to a meter thick and are formed locally. In contrast, the giant quartz vein systems, tens of kilometers in length and up to 3 kilometers in depth, are hosted in brittle-ductile

    01/01/2007· Gold and silver in massive sulphide ores occur mainly as electrum grains 1 to 20 μm in size. Microprobe analyses of five grains give Au contents in the range 52.34 to 70.28 wt.% with a mean of 61.47 wt.% (Liu et al., 1994). Most of the electrum occurs as inclusions in chalcopyrite, pyrite and pyrrhotite, as well as in gangue minerals. 5.8. Galena

  • Minerals Gekko Systems

    Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold recovery. Sulphide Gold Recovery.
