Results of the recent developments of J.C. Steele&Sons Inc. do show that the stiff-extrusion technology can be very efficient for the agglomeration of disperse anthropogenic and natural metal containing and carbonaceous substances. The Brex (Extrusion Briquettes) have a mechanical strength sufficiently high for the transportation and for the stockpiling for further strengthening storage at the moment of extrusion through the die. We have investigated the cold (mechanical) strength, the behavior during heating under the reducing atmosphere as well as the hot strength (in accordance with ISO Standard) of the Brex made of the metallurgical sludge, iron-ore concentrates, manganese ore fines, coke breeze and coal. The results show that the metallurgical properties of the Brex allow for their successful utilization in various processes of the extractive metallurgy.
