Hydrogen plasma smelting reduction

The HPSR process offers a one-step unit process for the reduction, melting and refining of ores. The process is currently studied for the reduction of iron ores, residues and chromite.

Highlights

• Mathematical model for the HPSR (H2PlasmaRed).
• Dephosphorisation kinetics in the HPSR (SusMet4Planet).
• OES-based monitoring (H2PlasmaRed).
• Pre-reduction of raw materials (TOCANEM 2).
