flotation process gold ore

  • Free Gold Gekko

    If the ore product contains a combination of coarse and fine free gold the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron the particle weight is too light for physical separation by gravity therefore gold recovery will require a modular chemical flotation process.
