Flotation Columns

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.
