fluorite grinding hardness

Mohs scale of mineral hardness Wikipedia

The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly. The samples of matter used by Mohs are all different minerals. Minerals are chemically pure solids found in nature. Rocks are made up of one or more minerals. As the hardest known naturally occurring substance when the scale was designed, diamondsare at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given

University of Minnesota’s Mineral Pages: Fluorite

However, fluorite’s intermediate hardness, perfect cleavage in four directions, and common fluorescence should allow it to be easily distinguished from other minerals that share a similar appearance. Quartz: At first glance, fluorite crystals may be mistaken for quartz crystals, especially the purple variety of quartz known as amethyst.
