WebHowever in graphite each carbon atom only bonds to 3 others around it- this means there is an electron spare which becomes 'delocalised'. This means that it is donated to form a common pool of electrons which can flow through the molecule carrying charge and so conducting electricity. Answered by Aneesh S. • Chemistry tutor. Graphite occurs in metamorphic rocks as a result of the reduction of sedimentary carbon compounds during metamorphism. It also occurs in igneous rocks and in meteorites. Minerals associated with graphite include quartz, calcite, micas and tourmaline. The principal export sources of mined graphite are in order of tonnage: China, Mexico, Canada, Brazil, and Madagascar.
