Solid state reduction of Panzhihua titanomagnetite

Reduction experiments were performed in a furnace which controlled the temperature to within ±5 C. In each experiment the titanomagnetite concentrates and pulverized coal or pre-oxidized sample additive and pulverized coal with a molar ratio of carbon to iron of 1.5:1 were completely mixed by rigorously stirring for about 30 min.

Solid State Reduction of Preoxidized Chromite-iron Ore

The model can provide satisfactory explanations for the reduction mechanism of natural chromite ores or chromite pellets. 1016 However it lacks detail investigation on coal-based solid state reduction of pre-oxidized chromite-iron ore composite pellets and it is also poorly understood the reduction behaviors of chromite-iron ore pellets

Direct Reduced Iron and its Production Processes – IspatGuru

Direct reduced iron DRI is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction DR processes.

Direct reduced iron - Wikipedia

Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes one example being heating iron ore in a furnace at a high temperature of 800 to 1200 C 1470 to 2190 F in the presence of the reducing gas syngas
