Flotation Agent - an overview ScienceDirect Topics
The mineral and mining industry is an extremely important area which utilizes bubbles in flotation to separate valuable minerals from ores. This separation process exploits the use of chemical flotation agents to modify the hydrophobic nature of mineral particles. It enables the air bubbles to selectively collect the valuable particles, the resulting bubble-particle aggregates then rising (i.e., floating) to form
