The reverse flotation of the iron ore with etheramine collector is significantly impacted when the iron-bearing silicates and the kaolinite are present in the silicates gangue mineral complex. This paper aims to propose a new amidoamine collector N-[3-(Dimethylamino)propyl]dodecanamide for iron ore reverse flotation with a potential of removing the iron oxides depressant.

collector for flotation of iron ore

The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates. Flotation collectors optimized performance. higher-grade iron ore concentrates with fewer impurities are requested by the steel industry. For more than 25 years, we have been developing flotation collectors in close collaboration ...

24.04.2019  For example, using dithiophosphate as collector of priority flotation in the copper and lead-zinc sulfide ore contains high iron sulfide can obtain high quality concentrates. At the same time, there are many kinds of dithiophosphates that have good collecting performance for gold. Moreover, because the dithiophosphate usually dissolves a small amount of sulfuric acid such as hydrogen sulfide or sodium sulfide, it is also suitable for flotation of slightly oxidized sulfide ore.
