Process development for production of high pure graphite from natural graphite

Advantages / Salient Technical Features Scale of Development
• Eco friendly process • Technology Demonstration (Current TRL
• Production of high pure graphite having more than Level : 07)
99% carbon
Commercialization Status
Problem being addressed • Commercialized
• By conventional process, it is not possible to produce
more than 95% fixed carbon from high grade graphite Techno-economics
ore. It is due to coating of the graphite on the surface • NA
of the gangue particles and mechanical entrainment
of gangue particles in the concentrate during the
flotation. Technology Package
• Concept to Design
Environmental Considerations (if any)
• Environment Friendly

Major Raw Materials to be Utilized
• Natural graphite

IPR Status / Details (India/Abroad)
• A novel route to produce high pure graphite : Indian
Patent 197530

Application/Uses
• Eco-friendly process to produce more than 99%
carbon in combination of chemical leaching and
physical beneficiation from natural graphite.
