Use of magnetic separation for purifying quartz for luminescence .

g/cm3 showed that only several grains of heavy mineral remained, mostly apatite and fluorite. Zircon, a luminescent mineral, is very rare in sediments and is highly unlikely to remain after magnetic separation. Magnetic separation is a common physical method used for separating minerals with different magnetic properties.

Fluorite - Wikipedia

It may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the surrounding "host-rock" in which valuable minerals occur) and may be associated with galena, sphalerite, barite, quartz, and calcite. It is a common mineral in deposits of hydrothermal origin and has been noted as.
