    Jul 23, 2014· 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 foam.

    The key factor will not be the flotation cell used, but rather the chemical conditioning that you use to make the chrysocolla hydrophobic. The mineral has variable flotation properties since it has an indeterminate copper concentration that ranges anywhere from about 20-35% Cu. Recoveries in conventional flotation tend to be unspectacular.
