| Abstract Scope |
Recycling spent Li-ion batteries (LIBs) has gained attention for its role in sustainability. LIBs are valuable sources of graphite, used in various applications. Froth flotation is a promising method to separate graphite from spent LIBs but faces challenges due to the adhesion of polyvinylidene fluoride (PVDF), which alters graphite's hydrophobic properties. This study investigates the impact of PVDF on the flotation behavior and surface chemistry of graphite, examining wettability, electrokinetic properties, dispersion behavior, and flotation reagent adsorption. Techniques such as SEM, TGA, FTIR spectroscopy, and surface charge analysis provide insights
into PVDF-graphite interactions. UV irradiation and ultrasound are explored to enhance PVDF desorption from graphite, improving flotation efficiency. These methods are assessed for their effectiveness in improving flotation efficiency. The findings indicate that these techniques significantly enhance the flotation process, offering an effective strategy for optimizing graphite
recycling from spent LIBs and contributing to sustainable resource recovery and waste management. |
