Coarse Particle Flotation
When treating uneven disseminated ore and large porphyry copper ore, coarse particle flotation can be taken into account. For hydrophobic sulfide ore, its coarse fraction by the separation of monomer will reach more than 200 μm, while for hydrophilic oxide ore and saline mineral, sometimes their coarse fractions by the separation of monomer ...
