Abstract
A useable particulate nepheline syenite having a grain size to provide an Einlehner Abrasive Value of less than about 100 is described. The particulate nepheline syenite is generally free from agglomeration and moisture free. At least 99% of the nepheline syenite particles have a size less than 10 microns. In practice, the nepheline syenite grain size is less than about 5 microns and the distribution profile of the particulate system is generally 4-5 microns.
