Höganäs Sponge Iron process is one of the major production processes used for iron powders. Here a solid-state reduction of iron ore concentrate with a mixture of coke, anthracite, and limestone is used to produce sponge iron units that are processed further to saleable iron powder products. The
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
