Jan 24, 2014The gold does not stay attached to the bubble in the froth of a flotation cell. Flotation as a method of recovering metallic gold is a poor way to go. Flotation works great as way to recover sulfides, including sulfides that have microscopic gold encased in them, but it does not work for recovering fine, free 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 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.
