Graphite output in 2005 World graphite reserves and mine production in 2022. Graphite is mined by both open pit and underground methods. Graphite usually needs beneficiation. This may be carried out by hand-picking the pieces of gangue (rock) and hand-screening the product or by crushing the rock and floating out the graphite.

An electric current is passed through the graphite rods which heats the mixture to 1700–2500 °C. [1] The result of the carbothermic reaction is a layer of silicon carbide (especially in its alpha and beta phases) [1] forming around the rod and emission of carbon monoxide (CO). There are four chemical reactions in the production of silicon ...
It has been in production since late 2007. [6] In 2021 the Mine produced 1,228,500 tonnes of finished products, up 46% compared to 2020. This included 1,119,400 tonnes of ilmenite, up 48% compared to 2020. Kenmare is targeting ilmenite production (plus associated co-products) of approximately 1.2 million tonnes per annum on a sustainable basis. [7]
