During the flotation process, the surface of fluorite and calcite is prone to partial dissolution, which makes the surface ions convert to each other. Moreover, the pH value of the slurry has a greater impact on the conversion of the two minerals. Therefore, the flotation separation of fluorite and calcite poses a great challenge.
