Ceylon Graphite Corp. (“Ceylon Graphite” or the “Company”) (TSX-V: CYL) (OTC: CYLYF) (FSE: CCY) announced today that Dorfner Analysenzentrum und Anlagenplanungsgesellschaft mbH (“ANZAPLAN”) has certified graphite obtained from its K 1 exploration site meets the parameters of spherical graphite required for battery and energy storage applications.
These tests conducted by ANZAPLAN over the last month confirm Ceylon Graphite’s end goal of producing premium battery grade spheroidized product for prospective lithium-ion battery manufacturers and other energy storage end-users.
The spheroidization process converts the needle-shaped particles into spherical particles. For different battery applications different median particle sizes are required. The spherical shape is achieved using a combined mechanical spheroidization and classification unit. The spheroidization process is performed in the treatment zone while the classification process separates the spherical graphite product from generated fines.
Bharat Parashar, Chief Executive Officer of Ceylon Graphite states: “Another arrow to our quiver. We have now proved to the world that Ceylon Graphite has the ability to provide battery grade spheroidized graphite to battery manufacturers and energy storage companies. We have both large reserves and quality natural graphite. Our next steps will be to start tangible discussions with the major players in this fast growing sector and to start fabricating our own processing plants in Sri Lanka.”
TECHNICAL INFORMATION
The main quality parameters of spherical graphite products are tap density, shape of particles, surface area (BET), PSD (particle size distribution) characterized by ratio of D90/D10 and the purity of graphite. The tap density specifies the amenability of the product to compaction. This parameter is related to the shape and roundness of the particles and should be in the range of around 0.85 g/cm3 for finer spherical graphite products (D50 of 10 μm to ~ 15 μm) and > 0.95 g/cm3 for coarser products (D50 ~ 15 μm to 25 μm). The BET value is an indication for the compactness of particles; typical values are 6 to 8 m2/g. Both tap density and BET are strongly related to the PSD of the spherical graphite product. Tap density decreases with increasing particle fineness while the BET value increases. The ratio of D90/D10 gives an indication of the steepness of the slope of the PSD. For spherical graphite a ratio < 4 for finer spherical graphite products and < 3 for coarser spherical graphite products is typical, ensuring a narrow PSD.
Different D50 particle sizes for SPG are required for individual battery applications as follows:
- Grid storage: D50 ~ 25 μm
- Electric vehicles: D50 ~ 16 μm
- Hybrid vehicles and consumer electronics: D50 ~ 10 μm
In Table 1 the analytical results of SPG product CE SP S1 obtained from Ceylon Graphite flotation concentrate are exhibited. In addition typical uncoated spherical graphite products (Ref 10/Ref 26) were added for comparison. A product with a D50 value of 19.4 μm was generated.
All analyzed parameters of the obtained spherical graphite product are in the range of typical comparable products. SEM images display well rounded spherical graphite particles similar to products on the market.
Dorfner ANZAPLAN and its laboratory, based in Hirschau, Germany are accredited by the DAkkS-accreditation chamber, which is a signatory to the multilateral agreements of EA, ILAC and IAF for mutual recognition, meaning that analyses and testing by ANZAPLAN is internationally accepted. In addition, services by Dorfner ANZAPLAN are certified and approved by ISO 9001:2015 and ISO 14001:2015.
Dr. Sebastian Prinz of Dorfner ANZAPLAN, confirmed this result and added that Sri Lankan vein natural graphite is of high quality and presents an advantage over conventional flake graphite as the beneficiation effort required to achieve high grade spherical graphite is reduced.

About Ceylon Graphite Corp.
Ceylon Graphite Corp. is a public company listed on the TSX Venture Exchange (CYL:TSX-V), that is in the business of exploring for and development of graphite mines in Sri Lanka. The Government of Sri Lanka has granted the company exploration rights in a land package of over 120km². These exploration grids (each one square kilometer in area) cover areas of historic graphite production from the early twentieth century and represent a majority of the known graphite occurrences in Sri Lanka. Graphite mined in Sri Lanka is known to be some of the purest in the world, and currently accounts for less than 1% of the world graphite production.
