Abstract
The object of the invention was to provide a granulation process for the production of heavy zeolite granules in which the quantity of granulation liquid used would be a less critical factor, so that (co)polymeric carboxylates could be used as a dissolved constituent of the granulation liquid. This object is achieved by using a mixture of water, surfactants and (co)polymeric carboxylates as the granulation liquid, the content of surfactants in the granulation liquid being at least 10% by weight.
