New flotation flowsheet for recovering combustible matter from fine
Some fine/ultrafine coal particles may be produced during the grinding process. It is well known that column flotation is suitable for separating fine/ultrafine coal particles smaller than 74 μm (Cinar, 2009, Tian et al., 2017, Xing et al., 2017). Thus, flotation column separation was selected and used in the flotation process.
