flotation of iron ore is a recent example of such a process [1, 2]. In addi- tion, nowadays polymers very often are added either to aid filtration, to clean effluents or as grinding aids. These reagents can markedly affect other downstream processes such as flotation [3-10]. In such operations, selec-tivity can be affected through interactions between polymer and surfactant in …

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or is also known as "natural ore".
