Optimization of chlorite and talc flotation using …

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.

[PDF] Optimization of chlorite and talc flotation using …

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 …

Effect of clay crystal structure on froth rheology in flotation

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.

Efficient selective flotation separation of talc and …

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 ...

Talc Flotation | Encyclopedia MDPI

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 …

Talc Beneficiation Process

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.

Optimization of flotation parameters for talc …

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

Optimization of chlorite and talc flotation using …

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.
