    Jan 14, 2020 The main purpose of flotation froth is to gather hydrophilic minerals, improve mineral processing precision and decrease the difficulty of mineral processing. For example, copper, lead processing are much easier to achieve high-quality and high efficient separation. Froth plays a very important role in the froth flotation process

    Jun 24, 2019 Froth flotation process, which uses the difference in hydrophobicity of minerals, is employed in several industries (mineral processing and others) for fines processing. It is a process of upgradation of minerals by taking advantage of differences in physico-chemical surface properties between valuable and gangue minerals of two different minerals
