Further independent testwork done on lindi jumbo concentrate indicate that the flakes are highly suitable for the production of expandable graphite and graphite foils with expansion ratios of up 590 cm 3 g achieved i.e. an expansion ratio of 590 times. this compares very well to the average expansion ratio of 250 times of china sourced graphite.

Solution to the graphite or problem. 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.
