Towards a new process for the flotation of quartz

Traditionally, HF has performed two functions in the production of high purity quartz concentrates: Firstly, it has been used to activate feldspar prior to its flotation by amine collectors – thus enabling the separation of feldspar and quartz at low pH where the zeta-potentials of the former remains negative while that of the latter becomes close to neutral (Buckenham and …

Investigation of the flotation behavior and interaction …

The flotation test was carried out according to the flotation test flow as shown in Fig. 2. The flotation recovery of single minerals was determined by weighing the products and the remaining products in the cell. ... For quartz, the flotation recovery of all three particle sizes initially increases and then decreases. It can be observed ...

Feldspar flotation as a quartz-purification method in …

Separating quartz from feldspar is difficult due to similar densities and magnetic susceptibilities. A useful separation method for both minerals is froth flotation [12,13], which combines physical and chemical treatments, and is known as an effective method in the mining industry for the beneficiation of feldspar.'Feldspar' describes a group of framework silicates, mainly containing …

Insights on the Flotation Separation of Hematite from Quartz …

Iron ore is the main raw material of the iron and steel metallurgy industry, but quartz in iron ore reduces metallurgical efficiency and increases metallurgical costs. Therefore, iron ore desiliconization by flotation plays an important role in the iron and steel metallurgy industry. In this study, 4-tert-butyl-catechol (TBC) was designed as a collector to directly float out hematite …

Natural Quartz by Dodecylamine

between the flotation process and the flotation effect still need to be completed. In our previous work, we examined the influence of OCT, SDS, and CTAB surfactants on the flotation of quartz by DDA. It is found that all three surfactants can co-adsorb with DDA on the surface of the quartz, thus strengthening the hydrophobicity of the quartz

Application and Mechanism of Mixed Anionic/Cationic …

In order to enhance the reverse flotation effect of hematite, dodecyl trimethyl ammonium chloride (DTAC) and a mixed anionic/cationic collector of DTAC and tall oil were selected for flotation studies on quartz and hematite. Surface tension tests, FT-IR, XPS analysis, and molecular dynamics (MD) simulations were also conducted in order to investigate the …

Investigations on selective flotation separation of quartz …

Flotation tests demonstrated that DAMP exhibited superior flotation performance, particularly for quartz, and its selectivity was notably better than that of DDA. Optimal flotation conditions yielded concentrates with a TFe grade of 67.79 % and a TFe recovery of 91.26 % at a pH of approximately 7.34, using DAMP and starch concentrations of 20.0 ...

Synergy Effect between Sodium Oleate and Alcohol …

The reverse flotation of quartz is a critical process for the purification of iron concentrates after magnetic separation [1,2].In this process, quartz is activated by Ca 2+ or other multivalent metal cations followed by flotation with sodium oleate (NaOL) or other anionic collectors at pH 11–12 into a froth product, while iron-bearing minerals (hematite and …

Research Progress in Flotation Separation of Quartz and …

Quartz is often symbiotic with feldspar silicate minerals, which is difficult to separate and purify because of their similar physical and chemical properties. Flotation is the most effective method for the separation of quartz and feldspar. The main flotation methods for the separation of quartz and feldspar, such as hydrofluoric acid method, fluoride-free acid method and fluoride-free acid ...

A Comparative Study of Quartz and Potassium Feldspar …

Quartz used in this work consisted of commercially available high-purity quartz from Jardi pond SL, Madrid, Spain of granular particle size ranging from 100 mm to 1000 m. Kfs used was a commercial product from VICAR, S.A., Manises, Spain, which was in powdered form, 90% passing in 106 m in size. Before froth flotation experiments, the quartz-rich
