Froth–floatation is used to concentrate sulphide ores [Galena (PbS)].Cassiterite$\left(\mathrm{S}\mathrm{n}{\mathrm{O}}_2\right)$and Magnetite$\left(\mathrm{F}{\mathrm{e}}_3{\mathrm{O}}_4\right)$are oxide ores and Malachite$\left(\mathrm{C}\mathrm{u}{\left(\mathrm{O}\mathrm{H}\right)}_2.\mathrm{C}\mathrm{u}\mathrm{C}{\mathrm{O}}_3\right)$is carbonate ore.
