In this study, the froth flotation experiments were conducted in a flotation machine, with cell volume 1.5 and 4 L. Rougher flotation was done to separate the graphite from their gangue minerals. Kerosene fuel (C 12 H 23 ) was used as collector, and Flotanol 7026 plus methyl-isobutyl carbinol (MIBC, C 6 H 14 O) as flotation frothers for the ...

Microcrystalline graphite is a valuable non-metallic mineral that can be separated by flotation, a physico-chemical processing method that uses air bubbles to capture mineral particles. The size and stability of the bubbles, which depend on the type and amount of frother added, affect the flotation performance and the recovery of water …

Recently, graphite recycling from electrode materials through flotation has attracted much interest [25], [26]. However, the graphite size of the liberation products of these electrode materials is very fine, which can deteriorate the flotation recovery of graphite [26]. Diesel oil is an often-used collector for graphite flotation.

From 0.10 to 0.25 g, the graphite flotation recovery was decreased. From 0.25 to 0.50 g (Fig. 7 b), the graphite flotation recovery also decreased. When the β-cd weight was increased from 0.50 to 1.50 g, the graphite flotation recovery was similar to the high ash content part and reduced in comparison to the low ash content part.
