HBI

Iron briquettes are produced by reducing iron ore fines in fluid bed reactors with a counter current reducing gas (Fluidized Iron Ore Reduction). Due to their high density and metallization, low gangue and residual content, and inert character, Iron HBI is the ideal metallic charge for steelmaking.
Physical and chemical specifications of Iron HBI make a superior product for the merchant HBI/DRI market, as a result of a low level of fines generated during transportation and handling, as well as less gangue, higher carbon, and higher metallization than that found in other HBI/DRI products.
