reagents in iron ores flotation

The reagents used in iron ore flotation, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in iron ore are examined. The presence of some specific impurities other than quartz in iron ore, such as alumina containing minerals, i.e. kaolinite and gibbsite, and phosphorous, is detrimental and attracts penalties. The removal of these specific ...

The diverse effect of temperature on iron oxides and calcium-activated quartz flotation is also indicated; the flocculation-flotation process of upgrading fine-grained iron ores is highlighted; and the economic advantage of reverse flotation in high grade, coarse- or medium grained iron ore flotation …
