Abstract:

Steel mill by-product material briquettes or pellets and processes for making the same that results in a briquetted or cold agglomeration pelleted material made from by-product material and a binder comprising gypsum-free cement and sucrose residue for the briquettes or a binder comprising gypsum-free cement and, if required, a sucrose residue for the pellets.
