Which types of ore can be concentrated by the Froth Flotation …

Froth-Flotation method: It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.; Sulfide ores are preferentially concentrated by the froth flotation process.; As pine oil( hydrophobic) is used for the concentration of ore, it is preferably wet ( hence concentrate) sulfur ore due to its hydrophobic nature.

Physical, Chemical and Mineralogical Characterization of Fluorspar

The Fe-oxide mineral liberation characteristics results indicated that 81.11% of the grains are full liberated, while 16.17% are the middlings and 2.72% locked in gangue. Based on the results and a requirement to make high iron grade pellets, reverse flotation method was selected for concentrating Fe in the fluorspar tails.
