Flotation of graphite ScienceDirect
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 8As the graphite flake size is one of the most important quality indicators, so in the sorting method using multistage grinding, multiple sorting process in order to select the flake graphite as soon as possible Flotation commonly used collector for the kerosene, diesel, etc, foaming agent for the second oil, fourth oil, adjusting agent for the lime, sodium carbonate, inhibitor for the water glassGraphite ore flotation process introduction 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 graphiteEffects of emulsified kerosene nanodroplets on the
