In froth floatation process,depressants helps to separate two sulphide ores by selective prevention of froth formation by one ore and allowing the other to come into froth. For example, in order to separate two sulphide ores ZnS and Pbs, NaCN is used as a depressant. It selectively allows PbS form froth, but prevents ZnS from coming to froth.
b Froth floatation process. This method is used for removing gangue from sulphide ores. In this powdered ore is mixed with collectors e.g., pine oils, fatty acids, etc. and froth stabilisers e.g., cresols, aniline which enhance non-wettability of the mineral particles and froth stabilisation respectively.

Froth Floatation Process YouTube. May 05, 2010 Froth Floatation Process Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Author TutorVista PDF Reagents used in the flotation of phosphate ores A
In the Froth Floatation process, zinc sulphide and lead sulphide can be separated by . A. using collectors. B. adjusting the proportion of oil to water. C. using depressant. D. using froth stabilisers.
Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic. Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
Froth Treatment Explained. Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation There are two different types of hydrocarbons used in Froth Treatment a naphtha-based hydrocarbon and a lighter paraffinic solvent Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable ...
What is the role of collectors in this process Froth floatation process is used when ore has wettiability towards oil while impurities have wettiability towards water. experiment on froth flotation. Froth flotation is the most widely used separation process in modern paper mills. During the last 10 years, the development of flotation de ...
froth floatation process manufacturers. Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic. Importantly the word flotation is also used in the literature to describe the process

High efficiency in the froth flotation process Easy to set up, operate, maintain froth floatation process Long service life flotation separation. Our engineer guide installation, connection and teach operation, also design according to your mine information like gold flotation, zinc flotation, copper flotation.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Frothers Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process Reduce surface tension of the liquid-gas interface to enable froth formation Hinder coalescence in order to stabilize bubble size
In froth flotation the effectiveness of an air bubble to adhere to a particle is based on how hydrophobic the particle is. Hydrophobic particles have an affinity to air bubbles, leading to adsorption. ... Collectors are the main additives used to improve particle surfaces.
