Sales of siliceous earth were increased over the last ten years from 40.000 to 50.000 tons per year. Based on this tonnage, presently deposits for at least 30 years have been explored. However, calculations count on further 100 years of exploitation. This is why another promising branch is being expanded aside from the siliceous earth. Already since the 1970s knowhow and capacities have been developed for the upgrading of Neuburg Siliceous Earth and other materials: the treatment of powder products with fine chemicals in order to confer to them improved properties for numerous applications.
