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.
Talc has found a steadily increasing number of uses such as cosmetics, steatite and cordierite ceramics, for pitch control in the paper industry and as a reinforcing filler in rubber, etc. In this research, the amenability of some Egyptian carboniferous finely disseminated talc ores to beneficiation by flotation was investigated on laboratory scale.
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.

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

Tests were conducted to assess the potential of column flotation for beneficiation of a talc ore from Montana. This ore contained approximately 80 pct talc, with the gangue comprised mainly of chlorite, silica, and dolomite.
Keywords: talc, chalcopyrite, flotation, separation, carboxymethyl chitosan Introduction Talc is a common gangue of copper-nickel sulﬁde ores around the world. Talc easily floats into a concentrate because of its surface hydrophobicity (Shortridge et al., 2000; Beattie et al., 2006). The Dongguashan copper mine is located in Tongling city, China.
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.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
The talc chlorite was improved to 82% by attrition in the presence of sodium hexametaphosphate at a pulp density of 76% . Beneficiation of talc-carbonate ore using polypropylene glycol as a frother was studied to increase the rate of talc flotation . A clean concentrate analyzing 93.5 % talc was obtained at …

Flotation of this superfine feed was conducted in the same conventional subaeration flotation cell. Aerofroth 71 was used as a frother for talc whereas soda ash was tested as …
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 effect of pH on the flotation recovery of talc in the absence and presence of chitosan is shown in Figure 4. It is evident that recovery is independent of pH. The recovery of talc is high (>80%) over the entire pH range in the absence of depressant. It is also clear that chitosan is a useful depressant for talc flotation.
