Montanwerke Brixlegg is constructing an industrial plant for the agglomeration of fine-grained, metal-bearing residual materials from the various aggregates used in copper production. The industrial extrusion of these recyclates depends on many different parameters. Within the scope of this thesis, these variables were investigated for their influence on agglomeration by means of literature research and experimental test series; moreover, recommendations for the development of recipes and process variants were derived. During the investigations, a bentonite was found to be suitable for both extrusion and solidification of the feedstocks. However, the main influence on the strength of the briquettes is the water content. A variation in the moisture content of 2-3 percentage points already causes a significant change in the uniaxial compressive strength. To achieve both higher strength after pressing and high final strength, the minimum moisture content must be adjusted by the correct ratio of dusts to slurries in order to be just extrudable. Upscaling towards industrial applicability from the stamp press (sample mass 800 g) to the laboratory extruder (sample mass 15 kg) was successfully implemented.
