Journal ArticleFlotation behavior of chromite and manganese-bearing minerals has been reviewed. Flotation of these minerals and ores with fatty acids, amines, sulfates, sulfonates and hydroxamates has been presented and is discussed in terms of surface charge and chemical interaction between the mineral surface and collectors. The role of metal hydroxy complexes such as FeOH+ , CrOH++ , MgOH+ and MnOH+ is also discussed
