1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while

The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.

· The flotation process involves adding various chemicals to the copper slag to make it hydrophobic, or water-repellent. This allows the copper to attach to air bubbles, which are then floated to the surface of the flotation cell. Once at the surface, the copper-rich froth is skimmed off and sent to a recovery tank where the copper is
