Lesser do we know about the processes used by graphite mining companies for graphite extraction from the Earth’s surface. Read this blog and gain a comprehensive idea.
Graphite is a semimetal native element which is an allotrope of carbon. Just like a diamond, graphite has interesting properties along with a chemical identity. The top graphite mining companies implement different techniques for its safe extraction. Let’s dive deep into the details.
Graphite Varieties And Uses
Depending on its nature, graphite has three major classifications.
- Crystalline Flake graphite
- Lump graphite
- Amorphous graphite
The use of the mineral dates back to the 4th millennium BC. People in the Neolithic Age in southwestern Europe made use of the Marita culture graphite for ceramic paint. Further, this paint was a necessity for decorating pottery. However, at present, natural graphite has uses in:
- Batteries
- Refractories
- Steelmaking
- Brake Linings
- Lubricants
- Foundry Facings
Graphene occurs naturally in graphite and is one of the most durable substances having unique physical properties. Prior to its functionality in any industrial operations, it demands certain technological development for separation from graphite. Other primary applications of graphite include zinc-carbon batteries that are a must-have in electric motor bushes.
In order to develop a heat resistant protective coating, railroads mix powder graphite with linseed oil or waste oil. They do this usually for the steam locomotive’s boiler portion, such as the lower part of the firebox or the smokebox. Historical references suggest that it was also known as the black lead or plumbago. Furthermore, graphite has classifications like microcrystalline graphite, macrocrystalline graphite and lump graphite.
Types Of Graphite Extraction
- Open Pit Mining
This type of mining generally takes place when the ore lies close to the earth. Additionally, the layer of surface material covering the ore must be thin. One can extract the microcrystalline or macrocrystalline graphite through open-pit mining because of its close proximity to the earth. Through quarrying, mining professionals mine graphite either by drilling or by using dynamite explosives.
- Underground Mining
Underground mining is for reaching the deepest ores. Several methods such as hard rock mining, shaft mining and drift mining are employed in underground mining. Borehole mining is common in both open-pit and underground graphite extraction. It prepares a slurry using the water through a tube. Then, the pumping of the water, as well as the mineral, takes place to the storage tank for further processing.
Besides, some industries use slope mining for extracting graphite ore when they are present parallelly to the ground.
