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.
