froth layer. Particles that are retained in the froth are recovered at the lip of the froth at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the and the recovery is sometimes assisted by mechanical paddles.
In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2 ), bornite (Cu 5 FeS 4 ) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.

I would think that you are not too worried about maximising the size of the graphite particles so gentle attrition is the way forward. You need to have a way to physically separate the clay from the graphite before attempting the separation, which would probably consist of classification (depending how fine the graphite has become) then flotation in the presence of dispersant at low percent ...
13.2.1 Ore Beneficiation by Froth Flotation. Froth flotation is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed. A concentration of 25–30% is suitable for economical smelting of copper.

graphite is mainly of vein type and the purities range from 90-. Demand for high purity graphite is progressively increasing due to its variety of traditional applications and predicted novel applications. Herein, we describe novel, low-cost and simple flotation technique for graphite concentration and crystallinity enhancement.
graphite flotation techniques Solution for Mining Quarry, SBMa Graphite Mining and Milling, carbon has been upgraded by froth flotation technique to produce . Froth flotation Wikipedia. Froth flotation is a process for, because the Bessel process was used on graphite not gold, In the 1960s the froth flotation technique was adapted .
Froth flotation takes place in a water-mineral suspension. It is used for selectively separating minerals by taking advantage of differences in their hydrophobicity. The surfaces of the graphite particles are hydrophobic (water-repellent) and it is thus very amenable to flotation in water using suitable/selective conditioning reagents.
Grade Microcrystalline Graphite Ore Flotation Using Multi-Stage Grinding-Flotation Process ... entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and ... prepared with a concentration of 50 wt % by ...
The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
