3 Cationic collectorsPrimary fatty amines, utilised in the pioneer U process, are no longer employed in the flotation of iron ores They were modified with the insertion of the polar group (O–CH 2) 3 between the radical R and the polar head NH 2 of the primary amine Due to the presence of the covalent bond C–O, characteristic of the organic function ether, reagents belonging to this Reagents in iron ores flotation ScienceDirect Queiroz (2003) verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the iron ore flotation and reagents netwerkoostkampbe A tremendous amount of research has been done on refining the flotation process for iron ore and designing the reagents which go into it This paper reviews the industrial practices and fundamental research surrounding iron ore flotationFlotation of Iron Ores: A Review: Mineral Processing and The role of reagents utilised in iron ores flotation is reviewed Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda Ether amines are by far the mostly utilised class of collector The degree of neutralisation of the ether amine is an important process parameterReagents in iron ores flotation ScienceDirect The new process is environmentally friendly, as only wellknown household reagents are used; oleic acid or tall oil, dextrin, sodium hydroxide and magnesium chloride at pH 105 Key words Iron/iron ores Environment Anionic flotation Mg activation Zeta potentialIron ore flotation with environmentally friendly reagents
