    OverviewTypes and varietiesOccurrencePropertiesHistory of natural graphite useUses of natural graphiteUses of synthetic graphiteGraphite mining, beneficiation, and milling

    Graphite , archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to . Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels.

  • Graphite Minerals Education Coalition

    DescriptionRelation to MiningUsesPure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another. This feature accounts for graphite’s distinctive greasy feel. This greasy characteristic makes graphite a good l在mineralseducationcoalition.org上查看更多信息
