method for processing staubfoermigen good metallurgical gases

摘要

A method is provided for processing dusts and muds from dust removing systems in the iron and steel industry by pelletizing them for further processing. Green pellets are formed by pelletizing the dusts and/or muds with a moisture content of between 10% and 16% for less than 6 minutes with an addition of water such that the moisture content of the green pellets is between 17% and 30%. The green pellets, together with a reducing agent, are then introduced into a rotary furnace.
