Flotation Reagent Flotation reagents have two important structural features a functional group consisting of donor atoms or ligands and a substituent group which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers or hydrophilic in the case of modifiers except for inorganic modifiers which comprise mainly inorganic bases and metal ions...

Method of flotation of sulfide copper-zinc ores includes the conditioning of the pulp in a calcareous environment with reagents-regulators sulfur sodium and zinc sulfate the introduction of collector and Frother and subsequent separation with separation of copper minerals in the froth reagents regulators additionally serves the reagent...

In the case of copper minerals the particles adhere to this froth which is separated whereas the great bulk of the useless material sinks to the bottom of the tanks By varying the chemical conditions within the cells different results can be obtained thereby making flotation highly selective in skilled hands...

Froth floatation method is used for removing gangue from sulphide or In this process a suspension of the powdered ore is made with water Collectors and froth stabilizers are added to it Collectors eg pine oils fatty acids xanthates etc enhance non-wettability of the mineral particles and froth stabilizers eg cresols aniline stabilize the froth...

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...
