Talc Beneficiation Process - Flotation
Talc: Part of 19 “Sub-A” Flotation Cells floating talc. Result: A concentrate approximately 94% talc produced at the rate of ¾ tons per hour. Flotation produces a uniformly pure product at a low cost per ton of ore processed and in addition recovers talc which cannot normally be recovered by dry processes.

Behavior of talc and mica in copper ore flotation ...
Talc is a naturally hydrophobic mineral, and therefore it is easily floatable. There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase.

The Art of Talc Flotation for Different Industrial ...
This allows talc to exhibit an inherent hydrophobicity, which is the basis of the separation of talc, by flotation, from other ore constituents in mineral industry. However, the heterogeneous character of talc surface particles has a particular importance in flotation.
Beneficiation of talc ore - Froth Flotation (Sulphide ...
Good day, please I need good info on talc Beneficiation. I have a large deposits of talc ore and I want to do away with the junk metals in the ore.
A novel method to improve carboxymethyl …
A novel method to improve carboxymethyl cellulose (CMC) performance in talc flotation is described in this paper. Micro-flotation results showed that using CMC as the depressant, strong depression on talc floatability was observed when the pulp pH was adjusted from low (4.0) to high (8.5), which improved the separation performance between ...
Beneficiation of Talc Ore - InTech - Open
Flotation is the preferred concentration technique to remove impurities from talc Kho and Sohn, 1989). Various factors that control the flotation process of talc include particle size, pH values, collector dosage, depressant dosage, pulp density and frother dosage which were
The effect of copper sulphate addition on the recovery of ...
Chromite and talc are two major gangue minerals in platinum bearing UG2 ore processed from the Bushveld Complex in South Africa. During flotation, talc is effectively depressed by the addition of depressants. Chromite, on the other hand, is considered to be hydrophilic, its recovery is believed to follow water recovery and

Experimental Study on Improving Grade of Talc …
1-11-2013 · The experimental sample consists of talc, magnesite and a little quartz, the grade of talc is 80%. By the floatation flowsheet of rougher and two times cleaner, and middling after regrinding return to rougher, the high grade talc concentrate can be obtained. The concentrate contains talc 95.67% (SiO2 61.68%). Talc recovery rate is 89.43%. By ...
Flotation separation of chalcopyrite from talc using ...
Flotation separation of chalcopyrite from talc using carboxymethyl chitosan as depressant 1259 The effect of carboxymethyl chitosan dosage on flotation of chalcopyrite and talc at pH 7 was studied and the results are shown in Fig. 4.
Selective flotation separation of molybdenite and …
All of the experimental results suggest that humic acids can be employed as a selective depressant for molybdenite during the flotation separation of molybdenite and talc under alkaline conditions, and the higher adsorption density of HA on molybdenite over talc is …
