ABSTRACT: Sri Lanka has its own demarcated possession for the high quality vein graphite containing 9598 % of initial purity of Sri Lankan vein graphite is exported as a cheap raw material without any value addition. The present study focuses to find a cost effective and convenient new chemical method for the graphite purification and to modify the graphite surface
tion process of graphite Sri Lanka is well known for high purity and high crystallinity vein graphite and they have Physical and Chemical Purification of the Sri Lankan Flake Graphite and Vein Graphite. Proceedings of 5th InSym, South Eastern University Sri Lanka,
Sri Lanka is the only area that produces commercial quantities of Vein graphite, which is also known by the names Ceylon graphite, Sri Lankan graphite, Plumbago and crystalline vein. As Sri Lankas premier graphite company, we aim to help the country tap this top resource as Sri Lanka has the highest quality of vein graphite which is believed to be formed by hydrothermal fluids.

#0183;#32;5. Purification of graphite. Purification of graphite is its physical separation from an ore mixture. This process can be explained by the thermodynamic principle of G M = H M TS M, in which G M, H M and S M are Gibbs free energy, enthalpy, and
graphite deposits occur at South Western region of Sri Lanka. The vein graphite deposits of Sri Lanka, located in a Precambrian highgrade metamorphic terrain dominated by granulitefacies rocks. Vein graphite becomes more attractive in Sri Lankan mineral index due to high purity (about 9599 % of pure carbon), extensive
A catalyst free process for manufacturing carbon nanotubes by inducing an arc discharge from a vein graphite anode and a vein graphite cathode in an inert gas atmosphere contained in a closed vessel. PROCESS FOR PREPARATION OF CARBON NANOTUBES FROM VEIN GRAPHITE Sri Lanka Institute of Nanotechnology (PVT) Ltd.
Vein graphite from Sri Lanka is unique and has its own niche market where present policies of the government impede growth. It forms in veins, a few centimetres to several meters in width.

Superior Graphites unique technology for hightemperature treatment/purification of carbonaceous materials is based on a resistantheated fluidized bed. This ElectroThermal continuous process is used to consistently treat and/or purify granulate calcined petroleum coke, natural flake graphite and other carbonaceous materials at temperatures approaching 3000#176;C. Through fluidization in an
Ceylon Graphite recently achieved an impressive % purity using a thermal purification process. Lithiumion batteries require a minimum purity of %. Sri Lankan vein graphite as opposed to flake graphite requires no primary processing before it goes to the purification furnace, allowing for a lower cost of production.
