Tests find MRL graphite
suitable for lithium batteries



MRL Corporation (ASX: MRF) has received a significant boost in
its strategy to become a lucrative graphite producer, with key
metallurgical test work showing its graphite exceeds the grades
required for use in lithium ion battery anodes.
Testing conducted at the Wuhan University of Technology (WUT)
found graphite from MRL’s Aluketiya project in Sri Lanka
contained 99.98% Total Graphitic Carbon (TGC).
Further test work will be conducted to refine the process flow
sheet and provide more detail on the suitability of MRL’s
graphite for premium-end product use.
Tests using an acid leaching process returned 99.66% TGC and
those using acid roasting returned 99.96% TGC. Testing is
ongoing with a view to simplifying the metallurgical flow sheet
and achieving grade of at least 99.95% TGC though acid leaching
techniques.
MRL believes the results were particularly pleasing because the
graphite used was the lowest-grade unprocessed bulk sample
material, which had an initial grade of 93.1% TGC. The expected
average grade of vein graphite to be mined by MRL is more than
95% TGC.
Typical high-grade Sri Lankan graphite achieves a greater
recovery rate than most disseminated flake graphite deposits
due to its reduced physical processing requirement and much
higher starting TGC purity
