ROTARY KILN (Coal-Based DRI Plant) ... (DRI) is produced from direct reduction of iron ore by a reducing gas produced from coal. The reducing gas is a mixture of hydrogen and carbon monoxide which acts as reducing agent. Rotary Kiln Process. The material is entered into one side of the kiln and as the rotation occurs, the material slides down ...
The Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Circored and Finmet / Finored gas-based processes utilize iron ore fines as feedstock.The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.
The iron ore deposits in the Labrador City area occur as specular hematite and magnetite, generally in the ratio of 65:35. IOC has mineral reserves and resources of 1.1 billion tonnes and 1.7 billion tonnes, respectively, with an average grade of approximately 38% iron.
