Response surface methodology (RSM), central composite design (CCD), and desirability functions were used for modelling and optimization of the operating factors in chlorite and talc (collectively termed 'mica') flotation. The influence of pulp pH, cyanide (NaCN) consumption, and particle size was studied with the aim of optimizing ssilicate flotation while minimizing …
Sulfidation-flotation is a commonly employed approach for floating oxide minerals using sulfidizers in order to sulfide the mineral's surface. In this research work, an oxidized sample from the …

A wetting agent, such as alkyl sodium sulfonate, made from petroleum products is generally used to float talc from tremolite and silica. Sodium silicate is sometimes used as a slime dispersant. 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.
Minerals 2021, 11, 662 3 of 19 Figure 1. The estimated total talc mine production in 2020 was 5.82 million metric tons. Data were extracted from USGS Mineral Commodity Summaries 2020 [19].
for sulphide flotation (Cao and Liu, 2006), but the presence of chlorite and talc, which have a natural floatability, lowers the grade of the lead concentrate. An additional 'mica' flotation circuit, upstream of the lead flotation circuit, is used from time to time to reduce the content of these silicate minerals in the feed to lead flotation.
The aim of the research work is to optimize parameters affecting efficiency of flotation process for obtaining high quality talc from talc carbonates of Mingora emerald mines, Swat, KP.
Therefore, this paper is the first attempt to optimize the molecular structure of exopolysaccharides and the optimal culture parameters of this strain to synthesize a green …
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...
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 …
The talc flotation showed that the IEP had little to no change when reagents such as depressants were added to the pulp, although the talc's potential decreased at certain pH due to shifting the slips surface double layer towards the outside. ...

This paper explored the different properties of talc and the different factors that affect its flotation separation performance as a proven versatile beneficiation technique.
The aim of the research work is to optimize parameters affecting efficiency of flotation process for obtaining high quality talc from talc carbonates of Mingora emerald mines, Swat, KP. Different parameters of flotation process like, pH, pulp
The nature of a clay mineral in aqueous solution is related to its crystal structure. Most clay minerals are phyllosilicates which are made up of silicon‑oxygen tetrahedrons (T) and aluminum‑oxygen octahedrons (O) in certain proportions [9].Montmorillonite (T-O-T), kaolinite (T-O) and talc (T-O-T) are common clay minerals present in froth flotation, as shown in Fig. 1.
The purpose of this work is to highlight and classify the investigations that were conducted on talc flotation, defining sub-areas of studies, and highlighting the areas that require further exploration for better understanding and optimizing of talc flotation.
3.2.1. Optimization of the pH value in talc flotation test Five flotation tests were carried out at different pH values, and at constant dosage of collector (1.0 kg/t), depressant (0.8 kg/t), and pulp density (200 g/l). The Chemical analysis results of flotation tests product are presented in Table 2a, which revealed that assay value of

The influence of pulp pH, cyanide (NaCN) consumption, and particle size was studied with the aim of optimizing ssilicate flotation while minimizing recoveries of galena, chalcopyrite, and sphalerite.
In the single mineral flotation, 2 g talc or molybdenite was added to a flotation cell with the volume of 60 mL and fully mixed at the rotation speed of 1800 rpm. Then, the pH adjuster, depressant, collector, and frother were added to the flotation cell successively, and the interval of each dosing was 3 min. ... In the optimization process ...
Central composite design, response surface methodology, and multi-criteria optimization using desirability functions were used to optimize the flotation of chlorite and talc ('mica') and minimize the loss of valuable metals (Pb, Cu, Zn) when there is a need to float the micas prior to the current process at CMG.
Optimization of flotation parameters for talc carbonates of Mingora emerald mine (Swat), Khyber Pakhtunkhwa, Pakistan. Engr. Sajjad Hussain. The aim of the research work is to optimize parameters affecting efficiency of flotation process for obtaining high quality talc from talc carbonates of Mingora emerald mines, Swat, KP. Different ...
During froth flotation, the more non-polar, friable talc (Mg3(Si2O5)2(OH)2) usually adheres to the surface of sulfide ore and floats up, causing difficulties in flotation separation and subsequent ...
