Question

Pine oil is used in the froth floatation process

Answer 1

Pine oil is an essential oil obtained by the steam distillation of needles, twigs and cones from a variety of species of pine, particularly Pinus sylvestris.
Chemically, pine oil consists mainly of cyclic terpene alcohols. It may also contain terpene hydrocarbons, ethers, and esters. The exact composition depends on various factors, such as the variety of pine from which it is produced and the parts of the tree used.


Well pine oil is used in froth flotation process because it does not have affinity towards water (because of the hydrophobic chemicals as its cconstituents)and it attracts impurities which can be washed away. 

Answer 2

Answer:

1. Pine oil is hydrophobic.
2. The particles of the metal sulphide ores which are hydrophobic get wetted by pine oil.
3. They float with the foam on the surface of water.
4. Thus, by using this property some ores which contain hydrophobic particles in tham can be concentrated by froth flotation process.

Hence, pine oil is used in froth flotation.
