Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
Froth flotation of scheelite – A review
When coarse, scheelite can be concentrated by gravity separation. However, as a brittle mineral (hardness of 4.5–5 on Mohs scale), it tends to slime easily during comminution. Finely grained scheelite is usually processed with froth flotation [3], which has only been the way to go since the 1970s [4].

Froth flotation process and its application
Froth flotation is one of the steps which is generally performed before roasting and it deals with the surface chemistry of liquids and of the minerals to be separated. This process requires a particular setup to be performed which contains different components. Surfactants play the most important role here.
A comprehensive review on the recovery of copper values …
Gravity concentration, froth flotation, roasting and leaching are the three primary routes discussed in the literature. Among all the methods, flotation has gained the attention of most researchers because of its cost economics [35]. The effectiveness of the flotation process relies on the choice of the suitable type and dosage of surfactants.
What Is The Difference Between Froth Flotation And Gravity …
The major advantage of froth flotation is that it is better at recovering fine particles than gravity separation, as the froth allows fine particles to float to the surface, while gravity separation is limited to heavier particles. Additionally, froth flotation requires less energy than gravity separation, making it a more cost-effective option.
