CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO ...
flotation has now expanded to include oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal. The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores.Learn more
