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.

FROTHERS FOR MINERAL FLOTATION - Ecolab USA Inc.

Frothers may act to stabilize air bubbles so that they will remain well-dispersed in slurry, and will form a stable froth layer that can be removed before the bubbles burst. Ideally the frother should not enhance the flotation of unwanted material and the froth should have the tendency to break down when removed from the flotation apparatus.

2014-5-27  A low grade graphite run-of-mine (r.o.m) ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily consists of quartz and graphite with minor quantity of mica. It analyzed 89.89% ash and 8.59% fixed carbon. The ore was crushed in stages followed by primary coarse wet grinding to 212 μm (d80).
