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.

Lime use and functionality in sulphide mineral flotation

Nov 01, 2019· In the process of sequential flotation, the use of depressants (e.g., Na cyanide, Zn sulphate, sodium sulphite, sodium metabisulphite) and activators (e.g. CuSO 4) at each stage is combined to carefully control pH to achieve optimum separation. Lime (or soda ash) is added to the different flotation stages to the required concentration.

Froth Flotation in Mineral Processing Minerallurgy

Flotation is a selective separation process, which is sensible to slurry conditions. For instance, pH value affects the adsorption mechanism of the collector significantly into particle surface. Lime soda ash and sulfuric acid are the most common pH regulators. The process of froth flotation begins by conditioning the pulp by adding
