Method of processing nepheline syenite |
| 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. |
