Flotation cells, the heart of the flotation process, create an environment where air is dispersed into the mineral slurry, forming bubbles that carry the mineral particles to the surface to form a froth layer. This layer is then collected, and the copper minerals are separated from the gangue.

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 ...

Flotation is a method that enables the separation of hydrophobic particles with the help of air bubbles (Fig. 3 a). In flotation, the particles adhere to air bubbles depending on solid, liquid, and gas contact phases. The interaction of particles and bubbles includes collision, adhesion, and stability [ 3, 4, 5 ].
