Oil Used In Froth Floation For Gold

Write scientific reason. Pine oil is used in froth flotation

Pine oil is hydrophobic. The particles of the metal sulphide ores which are hydrophobic get wetted by pine oil. They float with the on the surface of water. Thus, by using this property some ores which contain hydrophobic particles in them can be concentrated by froth floatation process. Hence, pine oil is used in froth floatation.

Flotation in Water and Wastewater Treatment

Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [1,2].Different bubble generation methods …

Froth Floation | Hoffman & Lamson Solutions

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

Principle of froth flotation. The differences in physicochemical surface qualities of distinct minerals are used in froth flotation. Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment, and for flotation to occur, an air bubble must be able to attach itself to a particle and raise it to the surface.
