Gold Recovery 101 Gold can be found in almost everything we see and touch; there are several important industrial uses for gold in electronics, dentistry and aerospace; however, almost 80% of gold ends up being used for jewellery. While jewellery is the end of the road for most mined gold, there are many ways it occurs in nature.

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.
