Summary
Total Graphite PLC has reported successful bench-scale test results achieving 99.2% Fixed Carbon (FC) purity from its Madagascan graphite using mild reagents. The company is now optimising the process to target 99.5% FC purity to supply high-value markets such as electric vehicle batteries.
Reasoning: Successful early-stage bench-scale purification of graphite to 99.2% FC demonstrates technical feasibility for high-value downstream products.
Positive factors
- Achieved high purity (99.2% FC) using mild reagents
- Targeting even higher purity (99.5% FC)
- High market value for target product (US$3,500/t)
- Environmentally conscious process (no HF required)
Negative factors
- Bench-scale results only; commercial scale not yet proven
Facts used in scoring: 1
Classification and evidence
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: The use of mild reagents and lack of HF requirement suggests a relatively simple purification process.
Evidence · text
“achieved purification of its Madagascan graphite up to 99.2% Fixed Carbon ("FC") by using mild reagents”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: The results are explicitly described as bench-scale test work.
Evidence · text
“bench-scale test work in conjunction with research institutes has commenced”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("concentrate")
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
