Gold flotation process is a kind of beneficiation method that makes the useful gold mineral adhere to the bubble to achieve gold enrichment by means of the different physical and chemical properties of the ore surface.. Gold Flotation Principle. Gold is an easyfloating mineral, so gold flotation process has always been one of the effective ways to process goldbearing ores.

② Gold is often dense associated with sulfide minerals, especially with pyrite,therefore, the sulfide minerals must be selected at the same time in the recovery of gold. ③ The relative density of gold is very large. In the process of flotation, the gold particles are easy to fall off from the bubble surface after contact with the bubbles.

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

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.
