Sep 10, 2002 · The range of carbon concentrations varies from 5% to 40%. Graphite flake can be found as a lamella or scaly form in specific metamorphic rocks such as limestone, gneisses, and schists. Froth flotation is used to extract flake graphite. “Floated” graphite has 80%–90% graphite content.

Flotation of graphite influences expansion and contraction of the cast iron during eutectic solidification and thus also interferes with seal feeding. Irregular distribution of the graphite results in inconsistent properties throughout the casting. The densiti difference between liquid iron and graphite is around 4.8 g/cm3.

Flaky graphite can be easily purified by flotation due to its high natural hydrophobicity [6,7].Generally, the flaky graphite ore was purified via multi-stage grinding-flotation (as shown in Figure 1a) to prevent the graphite flakes from being destroyed during the following regrinding, and a large amount of middling was naturally produced in the process [8,9,10].

Graphite consists of a stack of individual carbon layers in which the carbon atoms are arranged in a honeycomb structure, individual layers being weakly held together. This structure results in very good heat and electrical conductance within the layers, flexibility, high resistance to chemical attack and its highly refractory character.

Most low grade graphite ores are crystalline and respond very well to flotation treatment for graphite recovery. Where a fairly high percentage of the graphite in the comminuted ore is in the +100 mesh it is possible and sometimes desirable to screen out and recover the coarse fractions to market them as such. Coarse flake graphite generally commands a much higher price. On the other hand, where a maximum percentage of graphite in the concentrate is desired, the coarse fraction is recovered as s
