Froth flotation is a typical technique for separating rich minerals from gangue by choosing which air bubbles to attach them to. The froth flotation process is used by many flotation machines. Jameson Cell: The Jameson Cell is a high-efficiency flotation device that disperses air using a central draft tube and a downcomer to add air to the slurry.

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 separated ...
