The flotation machine, also known as a flotation cell or flotation separator, is a device used in mineral processing to separate valuable minerals from gangue (unwanted material) based on their differences in hydrophobicity (ability to repel water) and buoyancy. Flotation machines are widely used in the mining industry for ore beneficiation and ...
