Aug 10, 2019 Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife 5.5 and the hardness of quartz 7. In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.
The Bond Ball Mill Grindability Test is probably based on a laboratory grindability test first described by Maxson, Cadena and Bond 1934. The two tests are very similar. Both are locked cycle grinding tests. In both tests, the top size of the feed to the laboratory mill is 3.35mm, and the volume of
