Graphite extraction method– open pit, underground mining

Graphites are extracted by two techniques: the open pit method and the underground method. The economic value of the ore will determine the type of the mining to be used. Open pit mining. Open pit mining is generally used where the ore is lying close to the earth and the layer of surface material covering the ore is thin.
