Size & Model
Standard Form: Flakes (Irregular, leaf-like pieces)
Common Sizes: 0-3mm, 2-10mm, 10-25mm, or as required.
Also Available: Powder (various mesh sizes), briquettes.
We can customize the size to suit your specific process, especially for cathode precursor production.
Production Process
- Our Mn99.9 is produced through a sophisticated hydrometallurgical and electrolysis process.
- High-grade manganese ore is first leached and purified to remove impurities.
- The purified manganese sulfate solution is then electrolyzed in advanced cells, where pure manganese metal is deposited on the cathodes.
- These deposits are stripped, washed, dried, and crushed into flakes with minimal exposure to contamination.
