Title:

Process Development for Production High Purity Graphite from Natural Graphite
Value Proposition:

This is an eco-friendly process to produce more than 99% carbon in combination of chemical leaching and physical beneficiation from natural graphite. 
Summary Application:

By conventional process, it is not possible to produce more than  95% fixed carbon from high grade graphite ore. It is due to coating of the graphite on the surface of the gangue particles and mechanical entrainment of gangue particles in the concentrate during the flotation.To get high purity graphite (more than 99% of carbon) both chemical leaching & physical beneficiation process have been developed. 
Advantages:
  • Eco frinedly process 
  • Production of more than 99% carbon
  • Import substitution
