However, the most utilised early separation method, mineral flotation, is based on the surface properties of minerals. Flotation is a physio-chemical process that utilises particles' physical attachment to bubbles to separate minerals by floating them to the surface of flotation cells. Hydrophobic (or water repelling) surfaces can attach to ...
