In graphite ore, sericite is one of the main gangue minerals, and thus it is a major impurity in graphite flotation concentrate [128]. The study of entrainment property of sericite in amorphous graphite flotation revealed that the entrainment of sericite leads to the poor flotation selectivity of commercial microcrystalline graphite ore [95] .

Froth flotation is one of the most commonly used methods for the beneficiation of natural graphite resources [1,2,3,4].In graphite flotation, hydrophobic particles are selectively captured and transported by rising air bubbles, leaving hydrophilic gangue minerals in the suspension and discharging as tailings [].Therefore, bubble plays …

Amorphous graphite ore processing flowsheet Amorphous graphite ore has a high grade (generally containing 60% to 80% carbon), but the particles of graphite ore are extremely small and often embedded in clay, making flotation separation impossible. Therefore, many graphite mines directly pulverize and grind the mined raw ore to sell …

People …

However, the beneficiation of graphite ore is pivotal as it accounts for the quality, market price and suitability for various technological applications including energy storage in lithium-ion batteries. Since graphite is spontaneously hydrophobic (like coal) in nature, flotation is the common and apt technique for beneficiation of graphite ore.

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 …
