Talc Beneficiation Process - Flotation

Talc Market Specifications Talc has a wide variety of uses and markets, specifications for which call for certain standards of grain size, shape, color, chemical and mineral composition, weight per unit volume, oil absorption and hardness. The paint industry is by far the largest user of talc, but the roofing, ceramics, paper, rubber, cosmetics, textile and insecticide industries are important

Flotation separation of chalcopyrite from talc using a new

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.

Selective depression of talc in chalcopyrite flotation by

5/9/2020· Micro-flotation results show that xanthan gum severely depresses talc flotation but barely affects chalcopyrite flotation at pH 8. In artificially mixed minerals flotation, a concentrate containing 31.87% Cu can be obtained at 90.03% Cu recovery from a feed of 16.94% Cu, indicating xanthan gum as a selective depressant.

THE FLOTATION OF HIGH TALC-CONTAINING ORE FROM THE

79%) is partly a result of the high concentrations of talc. 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

Improved depression of talc in chalcopyrite flotation

5/12/2018· As talc has a strong natural hydrophobicity, it can easily float in the foam product during chalcopyrite flotation, thereby dramatically increasing the Mg content in the flotation concentrate [2,3]. Therefore, the effective inhibition of talc during chalcopyrite flotation has become the key to efficient exploitation and utilization of such copper resources.

The talc extraction and benefication from carbonatic talcose rocks -talc-magnesite, talc-dolomite and talc-magnesite-dolomite was done using flotation method in case study from Sinec deposit.

Selective flotation separation of molybdenite and talc by

1/3/2018· The results of flotation tests proved that both talc and molybdenite exhibit good natural floatability over a wide pH range (pH 3 to 9). The addition of HA could effectively depress the flotation recovery of molybdenite even at very low HA concentration (5 ppm).

Effect of Ultrasonication on the Flotation of Talc

The flotation results for monominerals, mixed minerals, and actual mineral samples indicated that guar gum exhibited much higher selective depression for talc than for scheelite.

Talcserpentine interactions and implications for talc

1/5/2012· It is evident from the picture that the flotation recovery of talc is independent of pH. The flotation recovery of talc is very high (>90%) over the entire pH range tested in the absence of CMC depressant. With the addition of CMC, talc is depressed and this depression effect depends on pH.

Effect of Ultrasonication on the Flotation of Talc

The flotation results for monominerals, mixed minerals, and actual mineral samples indicated that guar gum exhibited much higher selective depression for talc than for scheelite.

SURFACE CHEMISTRY OF TALC FLOTATION

Natural flotation of talc is dependent on pH and particle mesh size. Flotation recovery can be eorrelated with equilibrium solute concentration, suggesting that the aromatic alcohol possasses collector power. Apparent liquid specifie surface

Novel application of talc nanoparticles as collector in

The effect of flotation time on the collector dosage was found to be more significant for coarser talc nanoparticles. The results of this investigation introduce a new concept of natural hydrophobic talc nanoparticles acting as collector in flotation process.

Flotation separation of chalcopyrite from talc using

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

(PDF) Influence of shape characteristics of talc mineral

In this study, the flotation behavior of talc products having different particle shapes produced by different grinding mills (ball and rod mill) was determined by using column flotation process.

The effect of a novel depressant on the separation of talc

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.
