Froth floatation process is used the
Verified by Toppr. Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to ...

Lime use and functionality in sulphide mineral flotation: A …
Primary grinding – Lime is often added into the semi-autogenous (SAG) mill together with the ore feed and process water. Sulfide minerals are, by nature, acid to varying degrees causing the milled pulp to have a pH ranging from 4 to 8 depending on the sulphide and gangue mineral composition of the ore. ... Also, the flotation froth is more ...
Froth Flotation Principle and Process
Sulphide ore is shaken with pine oil and water in the froth floatation process, and the ore particles are adsorbed on the froth that floats, while the gangue particles settle down in the tank. Adsorption's role in the froth floatation process can thus be understood as the following processes: Pine oil adsorption on sulphide ore particles.

Froth floatation:is a physical method of separating mineral …
Froth floatation method is the physical method for the separating mineral from the gangue. (B) It is based on the difference in wettability of different minerals. The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. (C) Froth floatation process used for the concentration of sulphide ore.
Froth Flotation Process
"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in …
The Importance of pH in Flotation
In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important.
Sulfide Flotation
Sulfide minerals are often recovered by froth flotation where the galvanic interaction would occur, causing the electrons to transfer between them and making significant influence on the flotation process [93]. The electron transfer would change surface properties of sulfides, so the recovery of mineral would be promoted or depressed [94].
