Froth Treatment Explained | Oil Sands Magazine

Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

Froth flotation is one of the processes used to recover recycled paper.In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies.Normally the setup is a two stage system with 3,4 or 5 flotation cells in series.

Column Flotation

Today column flotation has become . an accepted means of froth flotation for a fairly broad range of applications, in particular the cleaning of sulfides (copper, zinc, lead and molybdenite) and the flotation of iron ore, phosphate and coal. Flotation columns differ dramatically from mechanical flotation machines in . several ways:

Froth Flotation |authorSTREAM

Froth flotation application Industries : Froth flotation application Industries Mining-the froth flotation process is used for the extraction of gold from gold ore, separation of sulfides, carbonates and oxides. Coal and phosphates are also upgraded by flotation technique.

Methods of recovering platinum

Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors. Bench-scale research showed that conventional matte smelting and ...

MEI Blog: Challenges in copper flotation

Sep 17, 2011· The development of froth flotation had an enormous impact on copper mining, enabling chalcopyrite and other sulphides to be efficiently separated from ores of relatively low grade and fine grain size. Until 1907 practically all the copper mined in the USA was from underground vein deposits, averaging 2.5% Cu, whereas flotation allowed the ...

Mineral Attachment and Bubble Bursting in Flotation Froths ...

Description. Mineral froth flotation is used to separate particles of valuable mineral from its associated gangue. It involves the selective separation of the hydrophobic particles from the slurry into the froth. As air is blown into the slurry, the hydrophobic particles attach to the air bubbles, while the waste particles remain in suspension.
