Abstract
A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.
