Well, froth floatation is a separation process on the basis of surface properties. The property which causes the separation of particles is density. Not all the particulate materials in practice are hydrophilic. So in order to have a separation, certain promoters and collectors are added. When the mixture is suspended in an aerated liquid, bubbles adhere to those particles which are difficult to wet by liquid (hydrophilic) and the effective density of the particle decrease and separation occurs.

Froth flotation process is used in the purification of sulphide ores. The ore is crushed into powdered, mixed with water and a little foaming agent and is vigorously stirred. The sulphide mineral forms a froth with the oil and stays on the surface while oxides and impurities settle to the bottom water layer.

Froth flotation is a process to purify sulfide ores, in presence of pine oil. The oil acts as hydrophobic agent and forms froth with hydrophobic impurities which is skimmed off from the surface leaving behind the concentrated mineral.

Why pine oil surround the concentrate only and water surround the gangue concentrate contains certain other elements as well so what compels the pine oil only to surround the mineral particles (concentrate) only?

Other oils can be used for froth flotation they can but the condition is that if and only if the other oils can reduce the density of water as pine ore does. Now find those oil.

Well pine oil is used in froth flotation process because it does not have affinity towards water n it attracts impurities which can be washed away.

Pine oil Forms froth with one the complex to refine the other ore. Actually, Froth flotation is used when there are two ores in one solution.

Froth flotation is based on wetting charactersitics of the ore and gangue particles with oil and water particles respectively.

Froth flotation is a process to separate hydrophilic (soluble in water) from hydrophobic (insoluble in water) materials.

Froth flotation means separate the hydrophilic and hydrophobic agents. So, pine oil used for metal extraction.
