Graphite processing in Papua New Guinea (PNG) is still in its early stages, but the country has shown potential due to its untapped graphite resources. Here’s an overview of graphite mining and processing in PNG:
1. Graphite Resources in PNG
– PNG has identified graphite deposits, particularly in East New Britain Province and other regions.
– The Nakru-1 project (formerly operated by Graphite Mountain Ltd.) explored high-grade flake graphite deposits.
– Other exploration projects are underway, but large-scale commercial production has not yet been established.
2. Processing Challenges
– Infrastructure: Limited roads, ports, and electricity hinder mining and processing operations.
– Regulatory Environment: PNG’s mining laws require foreign investors to navigate complex permitting and landowner agreements.
– Market Access: Exporting processed graphite requires reliable logistics, which can be costly.
3. Potential Processing Methods
If graphite mining expands, processing could involve:
– Crushing & Milling: Converting raw ore into fine graphite concentrate.
– Flotation: Separating graphite flakes from impurities.
– Purification (Chemical or Thermal): Enhancing carbon content for battery-grade graphite (used in lithium-ion batteries).
– Spheronization & Coating (for Battery Anodes): Advanced processing for electric vehicle (EV) markets.

4. Key Players & Projects
– Mayur Resources (ASX: MRL) has explored renewable energy-linked mineral projects, including graphite.
– Other junior miners are assessing deposits but face funding challenges.
5. Future Outlook
– If PNG improves infrastructure and investment policies, it could become a niche supplier of high-quality flake graphite for global battery markets.
– Chinese and Australian investors may show interest if exploration results prove economically viable.
