Reagents types in flotation of iron oxide minerals: A review: Mineral .

Nov 2, 2017 . Recently, beneficiation of iron from low-grade ores with high impurities has been a matter of discussion. Flotation is one of the most effective technologies for the upgrading of low-grade, finely grained iron ores. This method can also be applied to reduce the impurities content in magnetite concentrates.

The starch adsorbs on to hematite and quartz surfaces but the quantity of this reagent on to each mineral is different. So the selectivity between hematite and quartz in iron ore flotation happens because the starch absorption density on to iron minerals is bigger than on to quartz surface. So, when the collector amine that.
