Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores 4 In this process pyrrhotite as a primary impurity is separated from iron ore using typically potassium butyl xanthate as the primary collector The flotation process normallyReverse cationic column flotation technology is gaining traction in iron ore processing industry for recovering iron values from iron ore slimes/tailings Development and selection of appropriate collector suitable to the material to be processed

Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non floatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form3 Collector The iron ore concentrate of the first flotation cycle corresponded to the new feed material of the second cycle and was collected in a bin In this bin between the two cycles post conditioning was carried out with one addition of collector The sulfur bearing pyrite was directly floated and collected in
