Influence of physical and chemical parameters on ultrafine fluorspar
The formation of slime particles in processes of minerals grinding limits froth flotation. Minera de Orgiva S.L. (Spain) produces slime sludge containing 41.05% of CaF 2 from a fluorite ore. Slimes have a very small particle diameter with very high specific surface area making this material difficult to process by froth flotation even when the grade of the material is high.
