Froth_flotation - chemeurope

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

Froth Flotation Process - Detailed Explanation With ...

Apr 06, 2020  Basic Principle of Froth Flotation Process. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. First of all, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry.

Frothers Froth Flotation ArrMaz

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.
