WebGraphite Mining. Pure 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. WebA basic process is thermal treatment in the presence of caustic reagents to dissolve siliceous impurities such as quartz, feldspar or mica. The graphite concentrate is mixed with caustic reagent and calcined at elevated temperatures. After calcination the graphite is leached with water washing away dissolved impurities.
