Froth Flotation and Gold Extraction

This mixture is placed into a tank or flotation cell filled with distilled water. Air bubbles are pumped into the flotation cell and the water is agitated. Because of the surfactant, the gold is repelled by the water into the air bubbles, which rise to the top – creating a bubbly gold .

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Recovering Gold through the Froth Flotation Process

Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a large tank filled with distilled water.
