HYFOR (Hydrogenbased FineOre Reduction) is a novel direct reduction process for iron ore fines concentrates from ore beneficiation, developed by MHI Group company Primetals Technologies. It builds on fluidizedbed reduction technology, does not require any agglomeration (such as sintering or pelletizing), and uses on hydrogen as a feedstock.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
