Jan 02, 2012· In the reverseflotation of iron ores,froth washingwas found effective in reducing the loss ofFINE iron oxide particlestofroth. It was reported that the cost ofinstalling a column flotation circuitis approximately 25% - 40% less than an equivalentflotation circuit of mechanical flotation cells[60].

moreNow a days, for thebeneficiationof majoriron ore,froth flotationis popular. For effective flotation, the feed should be finer than 65 mesh.Anionic flotationemployingfatty acidor petroleum sulfonate collector is adopted to float out most of theiron oxide mineralsleaving behind the gangue, minerals (quartz & clay) in the tailings.
moreThe principal separation iniron ore beneficiation, therefore, is between theiron minerals,hematiteand/or magnetite, andsilica, principally in the form of quartz. The use offlotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejectingsilicafrom theseiron ores.
