Abstract: Specifically identified products are produced using powder formed from particles of a naturally occurring organic oxide mineral with substantially no free silica, preferably nepheline syenite, where the powder is essentially dry with a moisture content of less than 0.8% and has a controlled maximum particle size with 99.9% of the particles of the powder having a particle size of less than 10 microns defined as “fine grain ultra-fine” powder, which fine grain ultra-fine powder is preferably less than 6 microns, and where the fine grain ultra-fine powder comprises 3-25% by weight of the identified product.

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.

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.

Abstract: A method of processing a useable particulated nepheline syenite including providing particulate nepheline syenite with a maximum first grain size; milling the nepheline syenite in a ball mill operated substantially dry to produce a dry feed stock with particles less than a given size; and, using an air classifier to remove particles having a second grain size from the feed stock to provide an Einlehner Abrasive Value of less than about 100. In practice the second grain size is less than 5 microns and the distribution profile is generally 4-5 microns. The product produced by the method is, thus, novel.
