Selective flotation separation of bastnaesite from calcite ...

For calcite, recovery sharply decreased to 10.44% when the concentration of XG reached 15 mg/L, which indicated that the above two minerals could be flotation separated in the presence of XG. As XG can chelate certain metal ions, its excellent flotation separation performance may be related to the concentration of metals on the mineral surface.

[PDF] Selective Flotation of Calcite from Fluorite: A ...

Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using citric acid ...
