In the normal sintering process carbon-containing dusts, e.g. blast furnace dust, are added to the sinter mix without any prior conditioning. Since the fuel contained in the dust burns out too rapidly, its ability to replace coke breeze in sintering is limited.  In a demonstration project a new method to produce pellets out of fine-grained carbon-containing dust was tested.  The results showed that much higher substitution rates can be realized with the pelletized blast furnace dust.
