The comminution of spent lithium-ion batteries (LIBs) produces a powder containing the active cell components, commonly referred to as "black mass." Recently, froth flotation has been proposed to treat the fine fraction of black mass (<100 µm) as a method to separate anodic graphite particles from cathodic lithium metal oxides (LMOs). So far, pyrolysis has been considered as …

The flotation method is widely used for the preliminary beneficiation of aphanitic (microcrystalline) graphite. However, there is limited literature regarding the effects of flotation reagents on the flotation kinetics of aphanitic graphite. In this study, six commonly used flotation kinetic models were used to fit the flotation experimental data of aphanitic graphite. The …

Graphite flotation is widely used with good levels of recovery and efficiency, as it is a naturally hydrophobic mineral. Collectors traditionally used in graphite or coal flotation, such as kerosene and diesel oil, act on hydrophobic sites on the surface of the mineral particle, interacting through hydrogen bonds (Liao et al., 2020). However ...

The selective recovery of graphite through flotation was satisfactory. Best results were obtained at pH 8 and kerosene dose of 500 g/t, where carbon grade and recovery were 85.6 wt% and 85.1% for the fine sample (− 90 μm), and 84 wt% and 94.9% for the sample with particle size 90–420 μm, respectively.

Flotation is one of the most used methods to upgrade natural graphite resources. However, the efficiency is usually decreased due to the entrainment of undesirable fine gangue minerals.
