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

Flotation experimentsThe flotation experiments were performed on a laboratory flotator of Denver type with vessel content 1.4 L. The weight was always 100 g and tap water was used for the experiments. The flotation time was 10 min. The recovery at the end of a flotation test was determined by weighing the particles collected in the outgoing phase.
