Our Profile
Masan High-Tech Materials is one of the world’s largest processors of tungsten raw materials with primary smelting/refining technology located in Thai Nguyen, Vietnam (Masan Tungsten Company) and secondary smelting/refining at Goslar, Germany (H.C. Starck GmbH). Masan High-Tech Materials’ raw material supply consists of:
- Nui Phao Mine – the world’s largest tungsten mine outside of China, a wholly owned subsidiary of Masan High-Tech Materials.
- Purchased tungsten concentrates and tungsten intermediates – we procure primary raw materials from the market to supplement our internal production, guarantee supply stability, and leverage free market pricing and availability.
- Secondary tungsten materials – we procure all forms of tungsten containing scrap and revert.
Our process engineers and operators are experts in hydrometallurgy and have decades of experience in tungsten extractive chemistry. This enables MHT to get the most out of lower grade feeds, and ‘difficult’ to treat materials.
