1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O'Meara, 1939). (1979) reported that HF creates a large difference in the …
In this study, non-hydrofluoric acid flotation methods used in feldspar-quartz separation were compared with each other and conventional HF/amine method.
With feldspar the entrained free quartz was first removed by additional selective flotation (without and with surface preparation) after which a combination of acid leach and magnetic separation ...
Depressants are an important factor affecting the flotation selectivity of minerals. However, there are very few studies on depressants for flotation separation of quartz and feldspar (Feng et al., 2018).Flotation depressants can generally be divided into two categories: organic and inorganic depressants (Wang et al., 2020).The effective …
A new collector prepared using decyloxy-propyl-amine (DPA) and α-bromododecanoic acid (α-BDDA) at a molar ratio of 1:1 increased the difference in the recovery of spodumene (82.14%) and feldspar (32.48%) significantly [53].The difference in recoveries of spodumene and feldspar was 27.47% while using DPA only, whereas the …
Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery methods are economically limited to about 17% Al2O3. The problem in feldspar flotation is to recover slime free …
As our previous research shows, the pure sample of spodumene and feldspar was obtained from the Jiajika Lithium Mine, Ganzi District of Sichuan province, China (Tian et al., 2017a).After being handpicked, crushed, ground, and screened, the powder samples of spodumene and feldspar were screened to four size fractions (0–19, …
Potassium occurs abundantly in nature such as in seawater, certain clays and rock-forming minerals. The seawater is a source of potassium that contains around 380 mg/L, which constitutes approximately 1.1% of the total salt present [].It has been estimated that the total oceanic abundance of potassium is around 5.10 × 10 14 tons while the …
A dry high-intensity magnetic separator was used to upgrade feldspar ore minerals by removing the iron and titanium contents from feldspar concentrate obtained …
In order to investigate the flotation effect of BAA on spodumene and feldspar, we compared it with NaOl. The flotation recovery of spodumene and feldspar in effect of collector type and concentration are shown in Fig. 6. Table 7 is the flotation separation results of spodumene and feldspar binary mixed minerals.
However, the fatty acid dosages used to float hematite-which has a high concentration of Fe 3+ sites-are significantly lower than those used in spodumene or ilmentite research (10 −5 M vs. 10 ...
ABSTRACT Spodumene, a significant lithium extraction source, is primarily extracted from gangue minerals such as feldspar and quartz through flotation. Flotation is a process that relies on the difference in physicochemical properties of mineral surfaces. Therefore, it can be utilized to enhance the floatability of spodumene by means of …
This study demonstrates a high froth flotation separation selectivity between quartz and feldspar and that quartz can be readily floated in diluted HF solutions with …
1. Introduction. Elemental lithium is a desirable raw material, especially for the application in lithium-ion batteries and fuel cells that are currently attracting considerable interest worldwide [1], [2], [3].Spodumene (LiAl[SiO 3] 2), mainly found in silicate minerals, is regarded to be a lithium-rich ore of primary economic value [4].Froth flotation is one …
This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, …
In this work, an efficient collector, sodium N-oleoylsarcosinate (SNOS), was employed to achieve the separation of spodumene and feldspar. To investigate the flotation behavior and underlying mechanism, comprehensive approaches involving flotation tests, solution chemical calculation, Fourier transform infrared spectroscopy …
Intensified flotation of fine feldspar. Slimes in feldspar flotation (generally −38 μm size for feldspar mineral) have a negative effect on flotation by coating the …

The flotation responses of quartz and feldspar with alkylsulfonates' collectors in the presence of some alkaline earth metals were studied. The activation mechanism in these systems is discussed in terms of hemimicellization and surface precipitation of neutral component of cation-sulfonate complex, e.g. Ca(OH)RSO 3.. …

After the artificial selection of lepidolite and feldspar used in the experiment, large pieces of lepidolite and feldspar were selected and cut for the contact angle experiment, and the remaining minerals were crushed and screened to generate products with particle sizes of 38–74 μm and −38 μm, which were …
However, when Orhan and Bayraktar (2006) separated mica from a feldspar ore by flotation with tallow amine acetate as a collector and then separated iron and titanium oxide minerals using sodium oleate, they found that, in the presence of residual amine, co-adsorption of oleate on the feldspar occurred, resulting in the flotation and …
