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.
Hematite Processing by Flotation. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with SubA Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.
The relevant responses in iron ore reverse cationic flotation are silica grade and iron recovery in the valuable product. The flotation performance may be controlled via the dosages of amine (collector) and starch (depressant). Low amine dosages are desirable for this reagent is the most expensive.
Flotation Cells in Iron Ore Processing Froth Flotation
Flotation Cells in Iron Ore Processing (5 replies) The mixing and air dispersion actions on an induced air cell cannot be decoupled so this is more difficult. Also it is quiet difficult for a rotor located at the top to get sanded material in the bottom of the cell moving.
Keywords: Flotation Iron Ore Slimes . 1. Introduction . The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm . In Brazil, all the main pelletfeed producers use re verse flotation, being the tailing made up mostly of quartz

EFD is the world leader in column flotation technology with over 900 installations. Columns are used for floating wellliberated ores. Typically they produce higher grade and have lower power costs than conventional cells.
The increasing demand for highly enriched iron ore concentrate with low silicate and sulfide content as feed material for pelletizing systems also makes this technology very interesting for iron ore beneficiation. The company carried out a test campaign with its own Hybrid Flotation cell
