Flotation. Flotation experiments were carried out in a Denver D1 laboratory flotation device, using 1.5 l cell. First, 150 g of dry sample and 750 ml of fresh water were added in the cell and pH was controlled by the addition of NaOH or H 2 SO 4 solution. Subsequently, kerosene was added in the cell and conditioning was carried out at 500 rpm for 5 min. Methyl Isobutyl …

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

Froth flotation has been mostly examined to separate graphite as a hydrophobic part of the spent LIBs from the hydrophilic parts (mainly LiCoO 2). In the mineral processing plants (the main host of beneficiation processes), conventional flotation separation has been practically introduced for a limited size range (−25+150 µm).
