concentrate can result in inefficient smelter operations since it is a member of the spinel group that forms compounds that are stable to temperatures of up to 2000°C (McKenzie, 1996). As a result, there is a limit placed on the chromite grade obtained during flotation. The reagents used in flotation are designed to maximize the recovery of ...

These results therefore show that brighter, more pure talc products were obtained by using the alkanolamide alone or together with the alkylarylsulfonate frother. This indicates that the alkanolamide was more selective to the flotation of talc than the sulfonate was.

The microflotation results show that KG is a quality depressant for talc and that conditioning the minerals initially with PBX before KG will increase the recovery difference between pyrite and talc. result of talc flotation afropulseent. result of talc flotation September 25, 12 By CNMining 195 Comments.
• additional reagents to improve sulfide flotation • minimisation of recycles to limit ability of talc to reconnect with sulfides. Ore from the Mount Keith open pit can be broadly classified into two types: talc and non-talc. Non-talc ore is primary, unaltered ore consisting of predominantly disseminated pentlandite, pyrrhotite and
Process. 59 (2000) 215–224 219 It was found that in cases when the polymer concentration in solution was diluted during the microflotation test by adding deionised water to the launder instead of polymer solution, the flotation results of the talc were significantly different with respect to the guar, and fairly similar with respect to the CMC.
μm. 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 selective depressant of carbonate. In the mean-time, quaternary amine was employed in the laboratory as a selective collector for talc. 3. Results and Discussion 3.1.
Concentrate quality and flotation process of chalcopyrite are influenced as a result from the presence of talc. It is because that talc has inherent floatability which makes it readily mixed with the floated mineral and talc is easy to slime causing the slime coating of the valuable mineral (Beattie et al., 2006).
TALC (Soap Stone) TDAP. Steatite is a grade of talc suitable for making electronic tube insulators. Colors of TALC (Soap Stone) Talc Major Colors are White Grey Green Blue Pink Violet Silver It all depends upon the talc's chemical composition, and what proportions of such elements as
The result in Fig. 5a shows that after adding SGM, the flotation recovery of talc was reduced by 80%, while that of scheelite decreased slightly. At pH 9.0, the flotation recoveries of scheelite and talc were about 85.52% and 22.45%, respectively.
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.
Talcum Powder and Cancer American Cancer Society. Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen. As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes. It is widely used in cosmetic products such as baby
ABSTRACTThe depressant effect of chitosan on talc flotation has been studied and the results show that chitosan is a useful depressant for talc flotation and that its depression effect is independent of pH. However, the adsorption mechanisms are different at different pH values. In acidic solutions, chitosan behaves like a weakly charged polyelectrolyte, and electrostatic attraction is the ...
The results presented in Figure 3 showed that in increasing ionic strengths of synthetic plant water, the recovery of talc and the rate of flotation increased in the absence of CMC. However, an opposite trend was observed when CMC was added at 300 g/t in that there was a slight decrease in the rate of flotation of talc with increasing ionic ...
In the flotation of platinum bearing ores, guar gum is often used as a depressant for the talceous gangue minerals. In spite of a large number of studies conducted easier, the mechanism of adsorption of guar gum on talc has not yet been well understood. Mackenzie , Pugh , Healy  and Rath [5-6] proposed that the mechanisms that

Flotation separation of chalcopyrite from talc Based on the single mineral flotation results, the flotation separation tests of a mineral mixture, with the weight ratio of chalcopyrite to talc equal to 1:1, were studied and the results are shown in Table 2. It can be seen that the concentrate with Cu grade of
The results demonstrated that there could be a relationship between the deleterious effect of phyllosilicate minerals on the flotation and froth stability. Talc and montmorillonite have both shown ...

This trend is consistent with the results of flotation, showing that the treatment by HA increased the wettability of molybdenite much more than talc, and inhibited bubble attachment on molybdenite surfaces, lowering the recovery of molybdenite while not affecting the flotation of talc. 3.3.

IMPROVEMENT OF EGYPTIAN TALC QUALITY FOR INDUSTRIAL…. _____ 1817 with increasing pH value from 4 to 12. Conversely, the percentages of CaO, Al 2 O 3 and Fe 2 O 3 (the main wastes in talc) increased. These results are illustrated also in Figures 1a through 1e. From Figures 1a and 1b, it can be seen that, the SiO 2 assay
the depression of talc at a fixed room temperature about 25 °C through micro flotation and batch flotation experiments, zeta potential and contact angle measurements as well as infrared spectroscopy analysis. The flotation results displayed that the SAG had a significant influence on the flotation of talc but less inf luence on sulphide flotation.
Jan 15, 2019· 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 chalcopyrite and talc.
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.
