Properties of Commercial Iron Oxides for COREX Process
Research activities to classify the quality of iron oxides have a long history but most of such activities are for the existing processes such as blast furnace or DR plant. Therefore the newly developed process, such as the COREX process, needs new standardisation although some basic functions of the new process have similarity to the existing processes. Many researchers (Hauk, 1990; Cho et al, 1998) in the field of COREX process have conducted investigations since the early stages of the process development and activities are underway for further plant optimisation. As Agrawal and Oshnock (1995) pointed out, because coke is not included in the COREX reduction shaft the strength requirement of the feed materials in COREX process will be more demanding than that in the blast furnace. This condition is similar to Midrex DR plant but the main reduction gas of COREX plant is carbon monoxide generated from coal combustion while that of Midrex DR plant is hydrogen from natural gas.
