    2020-04-18  Hot-briquetted iron (HBI) is a compacted form of DRI designed for ease of shipping, handling and storage. Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore.
