Bastnaesite and magnesium-containing materials can be chemically reacted by use of reactions wherein alumina is made into a sol by use of a mono-protonic acid and then reacted with a magnesium-containing ingredient (e.g., magnesium acetate) and a bastnaesite ingredient such that, upon spray drying and calcination of the resulting composition, the bastnaesite is chemically reacted with magnesia to form a bastnaesite/magnesia/alumina compound having SOx activity.
