    The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example complex gold in a sulphide complex of pyrite must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises

    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.
