Fluorite - Wikipedia

Fluorite is a widely occurring mineral that occurs globally with significant deposits in over 9,000 areas. 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.

Summary of Fluorite Ore Flotation Process - JXSC Machine

Calcite type fluorite ore mainly consists of fluorite, and calcite( more than 30%). Since both calcite and fluorite are calcium-containing minerals, they have similar surface physicochemical properties. When coexisting in solution, they are prone to the mutual transformation between minerals, making separation of the two difficult to achieve. ...
