Froth Flotation Process FAQs
How does the flotation process work?
In froth flotation process, hydrophobic (minerals that reject water) and hydrophilic (gangue material that attracts water) minerals are separately separated. This is accomplished by adding air bubbles to a slurry of water and finely powdered ore.
Why is froth flotation used?
Froth flotation method is used because it is a very successful technique for extracting valuable minerals from gangue material in ores, froth flotation is used. It does this by taking advantage of variations in the surface characteristics of precious minerals, like copper, lead, zinc, and gold.
What is flotation with example?
Minerals can be separated from gangue material using variations in their surface characteristics, this process is called flotation. For instance, the addition of collectors makes the target minerals hydrophobic while keeping the gangue material hydrophilic in the flotation of sulfide ores, such as copper, lead, and zinc ores.
What is frother in flotation?
A chemical addition called a frother is used in froth flotation to help stabilize the froth and encourage the development of tiny, stable bubbles. By lowering the water’s surface tension, frothers enable air bubbles to stay in the flotation cell and raise hydrophobic minerals to the top. Pine oil and methyl isobutyl carbinol (MIBC) are common frothers.
Froth flotation process is used for which ore?
A variety of ores can be treated with the froth flotation method, including oxide ores (like iron, aluminum, and titanium ores), sulfide ores (like copper, lead, zinc, nickel, and molybdenum ores), and industrial minerals (like potash, phosphate, and graphite).
What is the principle of froth flotation process?
The selective attachment of minerals to air bubbles is the basis of the froth flotation process. The procedure takes advantage of variations in the surface characteristics of minerals; hydrophilic gangue material stays in the pulp, while hydrophobic minerals cling to air bubbles and rise to the surface as froth.
What is activator in froth flotation?
In froth flotation, an activator is a chemical addition that increases a particular mineral’s ability to float by increasing its surface receptiveness to collector molecules.
Froth Flotation Process
Froth Flotation is a very important process in the field of mineral processing which is utilized for the purpose of extraction of minerals from Ore. It is a part of surface chemistry in which we selectively separate the minerals from the unwanted material. This process is used in a variety of industries and is very crucial in each one of them. In this article we will look at this process in great detail.
