    Yet another gold removal process is flotation.The ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a foam. The collecting agent bonds to the gold creating an oily film that will later attach itself to the surface of air bubbles.

    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.
