Zusammenfassung:	Improved sparge compositions for froth flotation separation, methods of using them, and uses thereof are described. The compositions are suitably used in the froth flotation of particulate material containing ultrafine particles, and are well suited to the froth flotation separation of finely comminuted poor (low-grade) ores. The sparge compositions comprise functionalized silicone containing functionality that is tailored to the chemical nature of a beneficiary or a gangue in the ore. Sparging of the compositions effects improved recoveries and purities of beneficiaries. Sparge compositions and functionalized silicones suitable for the froth flotation of iron ores containing silica and/or silicate impurities are described. Sparge compositions and functionalized silicones suitable for the froth flotation of ores containing sulfur compounds such as sulfides are also disclosed.
