Where it comes from
Chart: Map of where it comes from
Graphite forms when carbon-rich rocks are cooked by metamorphism. Crystalline flake, the battery type, is dug from open pits, crushed and floated into concentrate.
Three things to know
- The US has mined no natural graphite since its last Montana output ended in 1989.
- Battery makers must qualify each graphite supplier before buying, so new mines struggle to break in.
- World reserves of 310 million tons equal about 172 years of 2025 output.
