Coarse gold floats badly. For largescale leaching of gold requires a lot of time. Fine gold is partly in a free state and partly in the splice (701 micron). Free fine gold floats well and quickly dissolves in the leaching. Using of gravity separation is possible, but it difficult. Fine gold .
If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higheryield 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.
