There were two main drivers for the development of the Circored process: the growing demand for a direct reduction process utilizing iron ore fines directly to decrease HBI production cost by avoiding a costly agglomeration step, and Lurgi's desire to apply its vast experience of utilizing fluidized bed technology also for direct reduction.
The current work and paper is based on a new iron production route which uses iron ore fines direct reduction. This technology was invented by ENRAG and PRIMETALS and is in ongoing development by Primetals Technology. It is called HYFOR. This new direct reduction technology uses iron ore fines instead of pellets and is …
