Minerals | Free Full-Text | Talc Flotation—An Overview

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.

THE FLOTATION OF HIGH TALC-CONTAINING ORE FROM THE …

Talc is naturally hydrophobic and therefore tends to float and report to the concentrate. During the experimental work done for this study, the author noticed that the presence of talc also changes the stability of the characteristics of the froth, resulting in difficulties in performing controlled flotation experiments. Therefore, in order to minimise the detrimental

Talc is a hydrous magnesium silicate, Mg3Si4O10(OH)2 , which is related to the sheet structure of the p hyllosilicate (Yehia and Al Wakeel , 2000[1]). However, natural floatability of talc is closely related to its three-layer sheet crystal structure (Fuerstenau et al., 2003 [2] and Fuerstenau .et al, 2007 [3]).

Flotation separation of molybdenite and talc by xanthan ...

Since the natural floatability of talc is better than that of molybdenite, flotation is usually used to remove part of the talc in advance to reduce the impact on the flotation of sulfide ore. At this time, the process of removing talc and the dosage of reagent are critical. When the amount of talc removed is large, it is prone to bring out the molybdenite during floating talc, causing the loss of useful minerals and …

20/10/2020· The flotation results indicated that carrageenan exhibited stronger depressing ability than the conventional talc depressants of CMC and guar gum, suggesting it could become a promising potential depressant in the selective flotation separation of chalcopyrite from talc. Adsorption mechanism of carrageenan on the surface of talc was investigated using zeta potential …

The flotation results displayed that the SAG had a significant influence on the flotation of talc but less inf luence on sulphide flotation. Compared with the depressant carboxymethyl cellulose (CMC) and guar gum, using of the SAG gave the highest copper recovery. It could not only eliminate a talc removal step, but also significantly decrease in the depressant consumption by half at least ...

Commercial talc may contain related sheet silicates such as chlorite and serpentine, and carbonates such as magnesite, dolomite and calcite2. When talc mineral is broken, two types of surfaces are formed, one surface results from the easily broken layers and the other from the rupture of ionic bonds within these layers. These surfaces are called as 'faces' and 'edges', respectively. The faces ...
