The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores There are, however, other impurities in some deposits that

First froth flotation is used Due to similarities in mineralogy there is not complete separation after flotation The gangue that is found with lithium after the flotation are often iron bearing The float concentrate goes through magnetic separation to remove the magnetic gangue from the nonmagnetic lithium See also Coal preparation plant

advantage of magnetic separation over flotation, in fine iron ore beneficiation is that treatment of –10 µm iron ore is possible – in flotation the feed is deslimed at 10 µm and the –10 µm stream is considered to be final tailings even though there is often a significant amount of contained iron ore The recovery of fine iron ore by magnetic separation will decrease with decreasing

· Reseparation, flotation, strong magnetic separation, or a combined dressing process Flotation is one of the common methods for separating fine to tiny particles of weakly magnetic iron ore In general, there are two frequentlyused processes: positive flotation and reverse flotation Iron ore beneficiation ways
