graphite, called amorphous, and flake graphite [2]. Graphite generally occurs as a result of metamorphism of organic matter in sediments. Flake graphite is assumed to be derived from the fine-grained sediments rich in organic matter. As metamorphic grade increases, carbonaceous material converts to micro-crystalline graphite [1, 3].

The current disposal techniques through landfilling or combustion are not environmentally friendly. Thus, methods for beneficiation of the waste are needed. Considering that chicken feathers are comprised of mainly keratin, it is plausible that the keratin can be exploited for application in biomedical applications.

Compared to amorphous graphite, flake graphite has a much higher market value (Table 1). However, the graphite produced by the froth flotation method is a blend of flake and amorphous graphite. Amorphous graphite should be separated from flake graphite for the greatest economic potential. For the same, air elutriation is employed.
