How Is Graphite Extracted? | Sciencing
Drilling and blasting methods are used on hard rock ore to liberate large-sized graphite flakes that are then crushed and ground before being subjected to flotation. The extracted graphite is brought to the surface by locomotives or, in developing countries, handpicked, shoveled and pulled in a cart and moved to the plant for further processing.
Graphite - Wikipedia
Graphite (/ ˈ ɡ r æ f aɪ t /), 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 diamond.Graphite is used in pencils and lubricants.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...

Graphite mining has taken place in the region of Lion’s holdings for over a century and specifically on Lion’s current mining permits for over 20 years. However, to date the methods used have been basic which has limited the output capacity but which also means that the majority of originally in-place reserves are expected to remain.
