There are two forms of graphite used in the world today, synthetic
and natural. Graphite (natural and synthetic) can be processed:
die-molded, extruded, isostatic pressed, expanded, reinforced and
coated. It can be transformed into yarns, foils and sheets, tapes,
boards, rigid and soft felts, powders.

Main physical processing steps applied:
- Comminution
- Flotation
- Micronization
- Spheroidization (spherical graphite)
- Intercalation (expandable graphite)
Main thermal and chemical processing steps applied:
- Thermal purification
- Acid leach
- HF free
- Caustic bake
- Caustic leach
