Iron ore pellets are an important refined product used as a raw material in steel manufacturing. In order to meet the requirements of the blast furnace process for steel production, the iron ore is upgraded in a number of steps including, among others, flotation. The induced hydrophobicity of the iron ore concentrate caused by.

Iron Ore - Clariant

In Reverse Iron Ore Flotation, Clariant has been developing a comprehensive range of collectors for iron ore flotation to remove undesirable silicate minerals impurities. The FLOTIGAM® series includes ether amines, used for hematite iron ore, and ether diamines, used for magnetite iron ore. The FLOTIGAM series.

The reverse flotation of iron ores is the usual process for the beneficiation of iron ores. In this case the silica particles are floated with amines. Usually this pulp, including the main part of amines, is deposited in the tailing dams. In the best case a part of the amine free water is reused as process water after a long residence.

to which a small quantity of flotation reagent is added. This reagent modifies the surface of either the iron oxide or the principal gangue component, normally silica, so that these particles attach themselves to the air bubbles and are carried to the surface, where they are removed as a froth. Flotation of iron ores can be done.
