what is the role of collectors in froth floatation?
Collectors as the name suggest are used for collecting the ore particles in the Sulphide ore. They are phillic to the ores. They are normally pine oil, fatty acids etc. They get separated from the froath mixture and helps to eliminate the ore from the gangue particles
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.
Collectors?are a type of surfactant that increase the natural hydrophobicity of the surface, increasing the separability of the hydrophobic and hydrophilic particles.?Collectors?either chemically bond via chemisorption to the mineral or adsorb onto the surface via physisorption.
