The process of machining graphite is identical to that of machining cast iron. Fine chips, often known as swarf, are extracted as fine powder. The devices used in the procedure do not grip the workpiece but cut it in a manner similar to plowing snow. The compressive strength of graphite is strong, and it may be kept in place by clamping force.

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Graphite is of metamorphic origin and usually found as veins, lenses, pockets. Depending upon the mode of occurrence and origin, it is graded into three forms: Flake - found in metamorphosed rocks as vein deposits. Crystalline (lumpy) - found as fissure filled veins. Cryptocrystalline (amorphous) - form in metamorphosed coal beds.
