On the contrary, limited Al sites on feldspar leave more space for BHA co-absorption with DDA on the surface of minerals, though after the sorption of DDA first. Thus, the flotation recovery of feldspar is higher than that of spodumene (Fig. 5). Download: Download high-res image (875KB) Download: Download full-size image; Fig. 9.

We achieved separation of quartz from feldspar with a newly built flotation cell for our feldspar-rich samples from the Pamir, Central Asia. Introducing flotation to the sample preparation procedure ensures quartz enrichment and mitigates problems related to contaminations with other mineral phases in 10 Be and 26 Al cosmogenic nuclide dating ...

of the flotation cell and flows over the lip of the cell, whereas the hydrophilic particles remain in the cell [14–16]. Traditionally, in order to achieve the separation of quartz and feldspar, the feldspar is floated from the quartz using hydrofluoric acid (HF) as the activator and the alkyl amine

Because spodumene and gangue minerals, such as feldspar and mica, have similar surface properties, that is, the Al site acts as the active center, the flotation separation of spodumene and gangue minerals using traditional anionic collectors, such as sodium silicate, naphthenic soap and fatty acid, is inefficient (Moon and Fuerstenau, 2003, Rai et al., 2011).

Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be …

The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O). Feldspar-silica22 mixtures can occur naturally, such as in sand deposits, or can be obtained from flotation of mined and crushed rock. 11.27.2 Process Description 1-2

Feldspar Flotation Process 【Process Introduction】 Process methods of fluorite (fluorspar) ore are gravity separation and flotation. Mineral processing equipment includes gravity separation equipment and flotation equipment; gravity separation ...

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 new combined collector of NaOL and 1,12-Dodecanediamine (DA122) was used for efficient flotation of spodumene from feldspar. The disparities in mineral flotation efficacy between the combined collectors of NaOL/1,12-Dodecanediamine and NaOL/Dodecylamine (DDA), as well as the underlying mechanisms, were comprehensively analyzed by the …

A method for recovering petalite from a mixture comprising petalite and feldspar minerals comprises the steps of forming an aqueous slurry of the mixture and adding to the slurry a depressant selected from the group consisting of alkaline earth metal chlorides, alkali metal chlorides, and mixtures thereof. Next, a collector comprising a quaternary ammonium salt is …

The low (<10%) flotation recovery of feldspar without an activator implies that any meaningful study of the flotation behavior of feldspar should be performed in the presence of an activator. The flotation response of feldspar particles of different sizes (0–19, 19–38, 38–45, and 45–75 μm) in the presence of Fe 3+ and using NaOL as ...

The utilization of a new collector 1-Dodecyl-3-methylimidazolium bromine (DMB) ionic liquid in the reverse flotation of feldspar from apatite was researched through a series of experiments. The micro-flotation results exhibited that DMB had a good collecting for feldspar while it had little floatability for apatite, and the artificial mixed ...

Complete flotation of quartz can be attained at 0.4 nonionic/anionic molar ratio Flotation separation of quartz from feldspar 1237 by using C12, C14, and C16 chain length sulfonates. Microcline is not floated in these systems and under the same conditions.

Quartz and feldspar cannot be efficiently separated using physical methods owing to their similar physicochemical properties. In recent years, flotation has emerged as the most effective method for separating feldspar and quartz (Larsen and Kleiv, 2016, Shu et al., 2020, Xu et al., 2020).Traditional flotation methods to separate these two minerals generally include …

the feldspar surface while depositing fluoride ions [15]. As a result of this mechanism, feldspar tends to be effectively depressed in the presence of collectors. Quartz could be easily floated, without using collectors, with HF solution and frother Brij C58 [19]. Selective flotation can be performed on feldspar from other impurities in the ...

The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na2SiF6; SF) as a selective depressant was investigated. Moreover, the influence mechanism of SF on the selective flotation separation of feldspar and …
