  • Physical and chemical interactions in coal flotation

    1. Introduction. Conventional froth flotation for fine coal cleaning suffers mainly from two problems (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles.
