The development of an emerging ironmaking technology is rapidly progressing. A 3-tpy pilot plant for the flash ironmaking process has been designed using lessons learned from lab-scale reactor testing. A unique solution for heating and cooling the ore and hydrogen reducing gas has been developed. The process consists of indirect induction heating of the iron ore in a falling particle curtain, where it is heated to 1,325°C and reduced to iron in 2–10 seconds. After reducing the ore, the falling particle curtain proceeds through a ruffled fin panel cooler to prevent particles from agglomerating.
