 — The full-scale REFLUX™ Flotation Cell, which is shown in Fig. 3, had an internal diameter of about 2 m. The upper vertical section had a height of about 1.6 m and the inclined channels were nominally 1.0 m long, with a 20 mm spacing and an inclination of 70° to the horizontal. As discussed, the feed slurry entered through an air sparger ...

 — The Jameson Flotation Cell Technology is owned by GlenCore. The heart of the technology is the machine's ability to create small uniform air bubbles.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

 — The collector and frother dosages were 100 and 70 g/t for larger flake graphite (HeiK) flotation and 200 and 140 g/t for smaller flake graphite (Jidong) flotation, respectively. The pulp concentration was kept at 60 g/L, the flotation cell speed was set to 2000 r/min, and the air charge was 250 L/h.

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 …
