China dominates global graphite production, supplying roughly 79% of the world’s natural graphite in 2024, with estimated output of 1.23 million metric tons. But significant deposits exist across every inhabited continent, from the tropical mines of Madagascar and Mozambique to the high-grade veins of Sri Lanka and emerging projects in Alaska. Where graphite is found depends largely on geology: it forms when carbon-rich sedimentary rocks are transformed by intense heat and pressure deep underground.
How Graphite Forms in the Earth
Every graphite deposit mined today traces back to the same basic process: carbon-rich sedimentary rocks, like ancient coal beds or carbon-laden mudstones, were subjected to extreme metamorphism over millions of years. The heat and pressure rearranged carbon atoms into graphite’s signature layered crystal structure. The type of graphite that results depends on the specific geological setting.
Thermally metamorphosed coal typically produces what’s called amorphous graphite, a fine-grained, lower-purity form. Crystalline flake graphite, the type most in demand for batteries, forms when carbon is disseminated through metamorphic rocks like schist and gneiss. The rarest and highest-quality form, lump or vein graphite, fills fractures in deeply metamorphosed rock and can reach carbon purities above 95%.
China’s Overwhelming Lead
China produced an estimated 1.23 million metric tons of natural graphite in 2023, dwarfing every other country combined. Beyond mining, China processes over 90% of the world’s graphite, meaning even graphite mined elsewhere often passes through Chinese facilities before reaching battery or industrial markets.
China’s major graphite-producing provinces include Heilongjiang in the northeast and Shandong in the east, where large flake graphite deposits have been mined for decades. Inner Mongolia also hosts significant operations. This concentration of both mining and processing has given China enormous leverage over the global supply chain. In 2023, China began implementing export restrictions on graphite products related to electrode manufacturing, a move expected to tighten supply through 2024 and 2025.
Africa’s Rapid Rise
Mozambique and Madagascar have emerged as the most important graphite-producing countries outside China, and by 2026 Africa could become the largest source of natural graphite for lithium-ion batteries. Both countries sit on extensive belts of metamorphic rock rich in crystalline flake graphite.
Mozambique produced an estimated 96,000 metric tons in 2023, down from 166,000 the year before. Its flagship operation is the Balama mine in the northern Cabo Delgado province, one of the largest integrated graphite mining and processing facilities in the world. Madagascar produced roughly 100,000 metric tons in 2023. One company operating there, Tirupati Graphite, scaled its annual production capacity from 3,000 to 30,000 metric tons in just three years. The Molo mine, developed by Canadian company Nextsource, is expected to become Madagascar’s largest graphite operation, and another project at Maniry is projected to generate $1.64 billion in revenue over the mine’s lifetime.
Sri Lanka’s Unique Vein Graphite
Sri Lanka holds a special place in the graphite world. It is currently the only country producing high-quality lump and chip graphite from vein deposits, a form prized for its exceptional crystallinity and carbon content of 95 to 98%. These veins formed when carbon-bearing fluids filled fractures in deeply metamorphosed rocks known as granulite facies, creating deposits that are unusually large and pure compared to similar veins found in southern India.
Graphite mining in Sri Lanka peaked during the first half of the 20th century, when over 2,500 pits and mines were active before World War II. Today, production comes from a limited number of underground mines, particularly the Kahatagaha and Bogala operations. Output is modest compared to China or Mozambique, but the quality commands premium prices for specialized applications in crucibles, lubricants, and advanced materials.
Brazil and Other Established Producers
Brazil is the world’s second-largest graphite producer by volume, mining an estimated 73,000 metric tons in 2023. Its deposits are concentrated in Minas Gerais state, where flake graphite occurs in Precambrian metamorphic rocks. Several active mines supply both domestic steelmaking and international battery supply chains.
Other notable producers include India, which has long mined flake graphite from deposits in Jharkhand, Odisha, and Tamil Nadu. Turkey, North Korea, and Canada also contribute to global supply, though at smaller scales. Norway hosts deposits in its Precambrian shield rocks and has attracted investment from companies looking to build European-sourced supply chains for the battery industry.
North America’s Push for Domestic Supply
The United States did not produce any natural graphite in 2024, making it entirely dependent on imports. That could change with the Graphite Creek Project on Alaska’s Seward Peninsula, about 55 kilometers north of Nome. It is the highest-grade and largest known large-flake graphite deposit in the country, with ore averaging 5.6% carbon in graphite form.
A 2022 prefeasibility study projected the mine could produce 53,600 dry metric tons of graphite concentrate per year. In response to surging demand for electric vehicle batteries, the company behind the project has undertaken additional drilling to support scaling production to 175,000 metric tons per year. If developed, Graphite Creek would represent the first significant domestic graphite source for the U.S.
Canada is further along. Quebec hosts several active and developing graphite projects, including the Lac des Îles mine, which has operated intermittently for years. Ontario and British Columbia also have deposits under exploration. Canada’s proximity to American battery manufacturing plants and its free trade agreements make it a strategically important source.
Why Location Matters for Batteries
Graphite is the single largest component by weight in a lithium-ion battery anode, which is why the geography of graphite deposits has become a geopolitical issue. With China controlling nearly 80% of mining and over 90% of processing, countries building EV supply chains face a concentration risk similar to what the oil market once posed.
The push to diversify explains the rapid development of African mines, the investment in Alaskan exploration, and new processing facilities planned in Europe and North America. For the graphite market, “where it’s found” is increasingly less about geology and more about which countries can build the infrastructure to extract it, process it, and deliver it to battery factories before demand outpaces supply.
