Abstract
The size of the particle plays an important role in the flotation of minerals. Comminution allows
the release of valuable species and their subsequent recovery. Then, the degree of concentration and
recovery will depend on the size of the particle. In this work, we investigated the flotation of coarse
particles (-850 +150 μm) of copper ores when using the fluidized-bed separator (HydroFloat® cell) and
compared it with the process of conventional flotation with medium size particle (-150 μm) (Metso cell)
using seawater. The collector concentration was the main variable studied in terms of copper recovery.
The results show that the flotation of coarse particles is feasible using seawater without frother
