Keywords: flotation, pH modifier, celestite, calcite, sodium oleate, concentration ores. 1. INTRODUCTION Somasundaran (1975) states that pH is the best factor with which to control flotation of most minerals, and that selecting a suitable pH value is essential for mineral separation.
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible.

Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
According to the effect of the agents, the flotation reagents are mainly divided into three categories: ing agent, collecting agent and metabolic modifier. (1) ing agent: the organic surface active substance distributed on the air-water interface, such as pine oil, cresol oil, alcohol, etc.

This branch of chemicals will prepare the mineral surface so other reagents will be able to collect the metal. For Conditioners and Modifiers, it may be simply cleaning the surface of the particles, as in the case of removing oxidization, or it may be a chemical that these are the chemicals that bind the mineral to the air bubble to be lifted away from the waste. Activators will attach itself ...
Jun 11, 2020· The reagents employed in flotation are generally interfacial surface tension modifiers, surface chemistry modifiers, and flocculants. Usually they are classified under five headings: collectors (sometimes known as flotation promoters), frothers, modifiers, activators, and depressors [1] .
Secondly, to supply flotation agent for global mining companies. We have a strong production base that can provide a variety of chemical products, such as Xanthate, Dithiophosphate, ing agent, Modifier Blue vil, White vil, Lead nitrate, Sodium metabisulfite, etc. and compound collectors.
This invention relates to a method for recovering a bulk concentrate of zircon and a bulk concentrate of rutile-ilmenite from dry plant tailings. A process has been discovered for froth flotation by manipulating the surface charges of dry plant tailings. Conditioning reagents, sulfuric acid to lower the pH; corn starch to coat the minerals to be depressed; sodium fluoride to activate the ...

Coal flotation with the use of additional modifying agents is studied. The modifiers used are represented by vinyl pyridine copolymers with alkyl sulfoxides. With the modifier flow of 0.5–1.0 g per ton of coal fines, the combustible recovery into the concentrate increases, with improved process selectivity and reduced coal organic mass losses with flotation tailings.

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).
Defination: Flotation reagent usually refers to a group of mining chemicals used to adjust the floatability of minerals in mineral froth flotation process, which can artificially increase the difference in wettability between various minerals, thereby achieving the separation of useful minerals and gangue minerals. The flotation reagent is mainly classified into three types:
This invention relates to the pH modifier in alkaline froth flotation processes to treat oxide and semi-soluble salt ores, such as phosphates, sulfates, carbonates and halides, to increase the recovery while generally maintaining or improving selectivity, thus the grade of desired minerals.
