1 U 3 0 8 is the symbol for a chemical compound, uranium oxide, composed of three atoms of uranium to eight atoms of oxygen. Most chemical assays for uranium are expressed in terms of U 3 0 8, and ore purchases are made on that basis.The uranium content equals approximately 85 per cent of the assay expressed in terms of U 3 0 8. 2 Hardness of minerals is related to Moh's …

Fluorite has a Mohs hardness scale of 4, making it relatively soft compared to other minerals such as quartz or diamond, but strong enough to be used as an abrasive in polishing and etching applications. This is crucial in mineral processing, as separating valuable ore from gangue minerals simplifies the extraction process.

There isn't a single ore mineral that makes up an entire ore deposit. The ore is almost always contaminated by gangue, a word for undesirable or non-valuable rocks and minerals. The ore and gangue are usually mined combined, which implies that a mass of ore and gangue is removed from the host rock using either mechanical or manual processes.
