Flotation of graphite ScienceDirect

1991-1-1  In the processing of graphite, the crude ore is subjected to crushing first to reduce to the desired size, followed by stage grinding in rod or ball mills in closed circuit with classifiers, before being sent to flotation. 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.
