Here only Galena is$\mathrm{P}\mathrm{b}\mathrm{S}$(a sulphide ore). Cassiterite is$\mathrm{S}\mathrm{n}{\mathrm{O}}_2$(oxide ore). Magnetite is$\mathrm{F}{\mathrm{e}}_3{\mathrm{O}}_4$(Oxide ore) and Malachite is$\mathrm{C}\mathrm{u}(\mathrm{O}\mathrm{H}{)}_2.\mathrm{C}\mathrm{u}\mathrm{C}{\mathrm{O}}_3$(Carbonate ore). The froath floatation process is used to concentrate sulphide ores, based on preferential wetting properties with froating agent and water.
