QA/QC and Process Optimization for Direct Reduced Iron ...

Direct Reduced Iron (DRI) is a method of purifying iron ores at lower temperatures, with lower energy needs and smaller scale plants. The DRI process uses natural gas to reduce iron ore to produce a "sponge iron" product with iron concentrations (90 – 94%) similar to that of pig iron. This sponge iron is an excellent feedstock for the ...
