Flotation separation of chalcopyrite from talc using ...Miner. Process. 53(2), 2017, ... To eliminate the adverse effect of talc on flotation of chalcopyrite, a frother MIBC was added to remove a talc slime before flotation of chalcopyrite. However, some copper minerals also float into the talc slime. Thus, selective depressants should be used to depress talc instead of appliion of a desliming flotation flowsheet. Polymeric reagents, such as CMC ...
Mistron® | ImerysTalc is hydrophobic and remains on the surface: the talcenveloped contaminants can therefore be evacuated during the flotation process. During cleaning, talc envelops stickies, increasing their density and making them easier to remove. Any remaining contaminants leave the process in the finished paper. Mistron ® can be added to the process at ...

DanafloatSince talc is generally fairly to very hydrophobic, the very fine talc slimes can adhere to air bubbles to such a degree that talc 'crowds out' the PGMcontaining minerals on the bubbles and therefore reduces PGM recovery. Typically CMC is used to depress the talc. Further, use of low frothing reagents is beneficial to minimize talc flotation. Often MIBC is the frother of choice because it ...
The effect of molecular assembly between collectors and ... · However, in the sorting process of copper sulfide ore, this method of dosing does not effectively separate sulfide minerals and layered magnesium silie minerals. In this study, the effect of adding a guar gum (as an inhibitor) and potassium amyl xanthate (as a collector, shortened as PAX) sequence to the flotation separation of pyrite and talc was investigated by microflotation tests ...

Talc Mineral ProductionThe process of alteration is in two steps: ... In this process, crude ore is grinded and crushed before the refining is done by flotation so that the content of talc and its whiteness can be increased. This all is done before using it as a mineral for industries. Talc can be produced by aluminosilie rocks. Talc remains stable when the pressure is high and temperature is about 700°C in ...
The effect of the ionic strength of process water on the ...Previous studies speculate that hydroxo species present in flotation pulps at pH > 9, particularly those of polyvalent ions, selectively adsorb onto gangue minerals. Such species supposedly enhance the depressive action of carboxymethyl cellulose (CMC) onto gangue via an acidbase interaction between the positively charged mineral surface and the negatively charged CMC molecule.
The Effect of the Ionic Strength of Process Water on the ...Figure 4 shows the flotation recoveries for talc under varying ionic strength conditions in the presence of CMC against time. Figure 4 shows that the recovery of talc had an apparent decreased slightly with increasing ionic strength of SPW. Also, the rate of talc flotation showed a slight decrease with increasing ionic strength of process water.

Talc Mining | Processing Equipment | Flow Chart | CasesWhat is Talc. The term talc refers both to the pure mineral and a wide variety of soft, talccontaining rocks that are mined and utilized for a variety of appliions. Talc forms micalike flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction.

The effect of the ionic strength of process water on the ...Furthermore, the zeta potential of talc particles became less negative at higher ionic strengths of process water. It is thus proposed that increases in the ionic strength of process water increased the zeta potential of talc particles, enhancing the adsorption of CMC onto talc. This in turn created a more coagulated nature on talc particles, increasing their hydrophilicity and thereby ...
