Froth floatation method is used to remove gangue from sulphide ores. Froth floatation process is used for the concentration of sulphide ores of copper, zinc and lead. 

Galena \mathrm{(ZnS)} is a sulphide ore of zinc.

Magnetite \left ( \mathrm{Fe_{3}O_{4}} \right ) is an ore of iron. Cassiterite \left ( \mathrm{SnO_{2}} \right ) is an oxide ore of tin. Fluorspar is halide ore of Calcium \left ( \mathrm{CaF_{2}} \right )

Since among the given ores, only galena contains sulphide ion, thus it is best concentrated by froth floatation method.
