ITmk3® process

The ITmk3 process, which produces high-quality iron (ITmk3 iron nuggets) from ore fines and coal fines, was developed based on a unique concept of iron ore and carbon composite technology. The development started in 1996, followed by test operations at a pilot plant and large-scale pilot plant. The first commercial plant was constructed in the U.S. and has started producing iron nuggets. This article outlines the history of the development, the features of the process, the product, and the future outlook.
