Effects of emulsified kerosene nanodroplets on the

2020-11-1  However, the main influencing factors of emulsified kerosene on the flotation of aphanitic graphite are its droplet size and stability. Peng et al. (2017) showed that the average droplet size in kerosene emulsions was related to emulsification conditions, such as time and energy. Smaller average droplet sizes had better separation efficiencies for fine graphite.

Flotation of graphite ScienceDirect

1991-1-1  In graphite flotation, a variety of nonpolar oils such as kerosene and fuel oil are generally used in combination with frothers such as pine oil or higher alcohol. In many respects, graphite responds to flotation in a similar way to coal or molybdenite. The pH of the pulp is usually adjusted to about pH 8.

It is also noted that the selectivity index in graphite flotation increases as the average droplet size of kerosene emulsions decreases. This is largely due to the synthetic effect of the mitigated gangue entrainment and the intensified collision between graphite particles and oil droplets in the presence of nano-scale oil droplets.
