Superior quality from the only vein graphite source on Earth
Sri Lanka is the only country in the world producing commercial quantities of vein graphite — also known as Ceylon graphite or crystalline vein graphite. Unlike flake or amorphous graphite, vein graphite forms when carbon precipitates directly from hydrothermal fluids, yielding extremely high crystallinity and purity without extensive processing.
Unmatched In-Situ Purity
Regadera mine graphite achieves 97–99.5% carbon content directly from the vein — equivalent to processed flake grades, with no acid treatment required for standard grades.
High Crystallinity
Superior crystal structure gives exceptional thermal conductivity, electrical conductivity, and lubrication properties — critical for batteries, refractories and advanced materials.
Purity Grades 80–99.5%
We supply a full range from industrial grade (80%) to ultra-high purity (99.5%) to match your exact application and budget requirements.
Responsible Sourcing
Small-scale underground mining in Sri Lanka minimises land disturbance and avoids the large tailings ponds required by surface-mined flake graphite operations.
