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.

Upgrading graphite by flotation at Bogala Mines in Sri ...

Graphite is naturally floatable due to its hydrophobic property and also soft and smears on other gangue particles, rendering the gangue more or less floatable too. Due to this reason it is important to concentrate on areas such as suitable flotation reagents, depression agents, pH modifiers, and particle size to be fed during the process. The paper surveys and analyses the suitable particle ...
