- Iron Ore Lump Washing Process
Lump Ore. High-grade lump ore is becoming increasingly more difficult to obtain with these ore bodies either in more remote locations, or miners are having to go deeper to mine them. There are several MIDREX Plants that are currently feeding lump ore in combination with DR-grade oxide pellets. Some of the advantages and disadvantages are:

Energiron direct reduction process (HYL process) uses a shaft reduction furnace to produce DRI. It is designed to convert iron pellet/lump ore into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO, for the production of highly metallized DRI.
