Jul 01, 2011· In the Laporte process, the ore is pre-oxidised in a fluidised bed at about 950 °C (Robinson et al. 1977) followed by reductive roasting in a rotary kiln using coal as reductant at ca 900 °C. The incomplete reduction of iron to the ferrous state without metallisation is achieved by the appropriate choice of equipment, temperature and reductant.
