01.04.2022Flotation 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 bubbles and be floated, whereas hydrophilic (or water attracting) surfaces cannot. Flotation, therefore, relies on valuable and gangue minerals
