Abstract
A method for preparing granulated alkaline earth metal carbonate, especially barium carbonate and strontium carbonate, by adding a binding agent and optionally water, and granulating the carbonate material by the action of mechanical forces or by accretional granulation in, for example, a flash reactor, with simultaneous drying, and thereafter optionally subjecting the granules to a high-temperature treatment, in which method the material to be granulated and the granulated material do not come in contact with inorganic refractory material either during the granulation or during any subsequent high-temperature treatment.
