The stretching of the C=C peak observed by XPS after flotation confirms the interaction of the collector with the mineral surface of the graphite, and this interaction is stronger between bio ester-graphite (16.50%) than with kerosene-graphite (15.53%), resulting in the ore grade performed better in flotation tests (assays 7, 8, 9).

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 …

ABSTRACT The micro-floatation of an amorphous graphite sample was conducted using a Hallimond tube with various droplet sizes of emulsified kerosene as collector. The results showed that the experimental recovery of the sample and the kinetic constants (both k and ϵ∞) obtained from the four kinetics models all increased with the decrease of the droplet size. …
