    Apr 24, 2019· 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.
