Abstract

The invention relates to a desulphurising flux comprising alumina dross formed into agglomerated particles of a size distribution of between 3 mm and 40 mm, preferably between 3 mm and 60 mm in maximum cross dimension by means of a suitable binder material. Also provided is a method of converting fine powdery alumina dross into such particles. Cement may be used as a binder material. The particles may be calcined.
