Particle size lower limit of 0.12mm, good separation effect, low operation cost, and convenient operation. Permanent magnetic drum type high-intensity magnetic separator.

The Bushveld Complex of South Africa contains almost 90% of the world's reserves of platinum group minerals (PGMs). In the flotation of PGMs, there are significant challenges arising from the need to treat ever-decreasing grades of the relevant ore deposits. The major challenge in the flotation of these ore bodies is the control and …

Our flotation cell, which has a volume of 600 cm 3, is built of borosilicate glass, holds up to 90 g of sample, and achieves quartz and feldspar separation in ≤2 h for very feldspar-rich samples. We trace the stepwise enrichment of quartz to 95- purity with our procedure by X-ray diffraction analysis.

Two samples yielded pure quartz concentrates, the remaining samples - very feldspar-rich initially - still contained up to 4.9 wt.% feldspar. After the froth flotation, these small amounts of feldspar will be dissolved during further chemical treatment, e.g., the first leaching cycle for the removal of atmospheric 10 Be by concentrated HF.

Feldspar is a common occurrence in spodumene ores, and has applications in glass making. K-feldspar is a key component in the manufacturing of ceramic materials. Froth flotation is the main method used for the recovery of feldspar from lithium ores because its flotation properties are well understood (Fuerstenau and Pradip, 2005). …

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, …

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 …

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and …

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.. …

Flotation is the most efficient and widely used method for separating feldspar from spodumene [6]. Spodumene and feldspar are both aluminum-containing minerals, the surface chemical properties of the two minerals are similar, and their surface active sites are mainly Al 3+ [7].

Therefore, although Fe(III) effectively improved the flotation of spodumene, it was not beneficial for the flotation separation of spodumene from feldspar and quartz. When Ca(II), Mg(II), and Cu(II) were used as activators, the adsorption amounts of α-BDDA on spodumene were significantly higher than those on feldspar and quartz, which led to …

The study also indicates that the use of anionic collector sulfonate alone has a negligible effect on the feldspar flotation due to non-adsorption of the collector on the mineral surface as is evident from the infrared spectra data. ... hydrothermally synthesised the zeolite A, from K-feldspar by treating the ore (of − 75 μm) ...

The flotation tests showed that dolomite and potassium feldspar can be successfully removed from apatite simultaneously when the molar ratio of DTAB to NaOL was 2:1 with pH 4.5.

Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10 −5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering/washing operation after mica flotation seems to be a crucial step. Feldspar recovery in the concentrate, being 86.67% without dewatering/washing ...

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric …

It is notable that the differences in flotation recoveries are 63.74% and 53.92% at molar ratios of 6:1 and 8:1, respectively, showing a tendency of diminution with increasing BHA:DDA molar ratio. The flotation recoveries of spodumene and feldspar are 88.31% and 24.57% at pH 8–9, respectively, at BHA:DDA molar ratio of 6:1.

Abstract and Figures. In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency ...

The results of the flotation tests show that feldspar and quartz without SF treatment have good floatability. After SF treatment, feldspar still has good floatability, …

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, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the published information on feldspar flotation relates to …

An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. 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 …

Feldspar minerals (KAlSi 3 O 8, NaAlSi 3 O 8, CaAl 2 Si 2 O 8) are the most abundant of aluminosilicate rock forming minerals, comprising 60% of the earth's crust.They are widely applied in the production of glass, ceramics, and as fillers and extenders [1,2] in the paper and paint industries.In order to improve the purity or the whiteness of feldspar, …

Abstract. Granite tailings are rich in quartz and feldspar with high recycling value. However, quartz-feldspar separation usually adds sulfuric acid and hydrofluoric acid, which inevitably leads to equipment corrosion and environmental pollution. This study introduced an alkaline-based flotation method to treat granite tailings.
