Froth Flotation Process

 · "The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different egories of hydrophobicity that are increased by ...

Flotation Reagents Collectors | ArrMaz

Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals. Once at the surface, the select minerals are supported by a froth layer until ...

A comparative study between the adsorption mechanisms of ...

iron ore concentrates, the content of these impurities should be at an acceptable limit (P ≤ % and SiO 2 < 2%).[5,8,9] Flotation is the most effective method for the separation of these impurities. Anionic and ionic flotations are mainly used to remove gangue minerals from iron oxide ores.[5,7,10–13] The removal of silie and phosphorus minerals (apatite group) has been reported ...

Dodecyl Mercaptan Collector for Sulfide Ores

 · On precious metal ores, dodecyl mercaptan resulted in strong flotation of gold values associated with iron sulfides. Gold recoveries increased from about 2 to 4 percentage points over those obtained with xanthatetype promoters. Pennfloat3 was also very effective for flotation of platinum group metals and resulted in an increase of 10 percentage points on one ore over that recovery obtained ...

New perspectives in iron ore flotation: Use of collector ...

 · The reverse flotation of the iron ore with etheramine collector is significantly impacted when the ironbearing silies and the kaolinite are present in the silies 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.
