  • The Classification of Graphite?

    The graphite minerals with various crystalline kind have various industrial value and use. In sector, in line with the distinction of crystalline morphology, all-natural graphite could be divided into 3 sorts: 1. Dense crystalline graphite: it's also referred to as blocky graphite. Such graphite crystal seems clear and its crystal may be visible. Its crystal arrangement is disordered and appears a dense mass structure.
