In this paper, a surfactant, atlox4862 (formaldehyde condensate of methyl naphthalene sulfonic sodium salt) (MF), was introduced as a depressant for reverse flotation separation of sericite from graphite. Natural flake graphite has a strong hydrophobic property. After interacting with MF, the graphite became moderately hydrophilic. The flotation results showed that MF had a depressing ability ...

Natural Flake Graphite | Asbury Carbons
Graphite from Canada runs 90-97% carbon and graphite from China 90-96% carbon. Careful control of the floatation methodology can generally improve the purity but floatation cannot reduce the level of "intercalated" mineral matter. The size of the graphite flake is a very important commercial consideration.

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 8.

Preparation of high pure graphite by alkali digestion ...
This paper deals with a novel new technique: alkali digestion, followed by grinding and flotation, has been attempted for the first time on the Indian graphite ore. The novelty in this method is that the quartz mineral, SiO 2, present in the flakes, releases during thermal shock treatment and dissolves partly with sodium hydroxide.
