Optimisation of gold recovery by selective gold flotation

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore even when a proportion of the gold is free Gold does float readily however and the free gold can be selectively floated away from

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 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
