Selective separation of Na- and K-feldspar from weathered granites by flotation in HF medium Ceramics Silikáty 54 (1) 60-64 (2010) 61 multivalent salts, a required selectivity in flotation is achieved . Sodium ions depress Na-feldspar during the flotation of alkali feldspar at natural pH and in HF
18.07.2013· Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine collector at neutral or acidic pH values. To overcome environmental issues when fluoride ions are used to activate the feldspar in the third flotation stage, fluoride free flotation conditions that utilise a combination of anionic and cationic collectors have been developed.
Sodium alginate (SA) was investigated for use as a depressant in the spodumene–feldspar system. In this flotation system, the SA is added before the cation collector, dodecylamine (DDA). The effects of SA on mineral floatability were systematically investigated by flotation experiments, X-ray photoelectron spectroscopy (XPS), Fourier
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 granular products, all minus 20 mesh, usually with not over
Excellent flotation results were obtained in the pH range 1.8-2.6. The function of Duomeen TDO is to selectively adsorb on feldspar particles and suppress quartz particles. The mechanism of tallow alkyl propylene diamine dioleate salt in the flotation of feldspar has not been definitely determined. However, it is certain that at low
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 increases to 94.58% after three stage dewatering/washing

Feldspar is a silicate mineral of K, NA, Ca composed of silicon-oxygen Tetrahedra. Its main components are SiO2, Al2O3, K2O, Na2o, CaO, and MgO, which are important raw materials for manufacturing, and widely used in chemical, abrasive,
Then hydrofluoric acid amine flotation is used to separate feldspar from quartz. Filtering-Drying. The spodumene concentrate is discharged at the tailing discharge of the flotation machine and is ready for final processing. The spodumene pulp contains approximately 20% solids and must be dewatered before filtration to reduce the volume of filtrate.
Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
In this study, results are presented of laboratory flotation tests and industrial application to separate colouring minerals (muscovite, biotite, rutile, sphene), some iron oxides and clays from Çine-Ceyhan sodium feldspar ore owned by Kalemaden A.S. In the first stage, conventional mica flotation was carried out at pH 2·5–3 by using tallow amine acetate as collector together with a
sodium, and calcium, and it is the most abundant mineral of the igneous rocks. 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 Conventional open-pit mining
WITH SODIUM HYDROXIDE ON ITS FLOTATION Fushun YU*, **, Yuhua WANG**, Abstract: Effects of NaOH on flotation of spodumene, quartz and feldspar using oleic acid as a collector were investigated through microflotation and bench scale flotation tests. It was determined that NaOH acted more than a pH regulator in the tests. The X-ray photoelectron spectroscopy revealed that
potassium feldspar lead zinc flotation machine ATMANDU. potassium feldspar lead zinc flotation machine Flotation is an effective way to remove impurities in feldspar On the one hand the impurity elements such as iron and titanium can be removed from feldspar the combination of stone agents depends on the existing components of impurity on the other hand the feldspar can be separated out
Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine collector at neutral or acidic pH values. Beneficiation of feldspar ore for application in the. The feldspar minerals and quartz were separated from each other by flotation of feldspar minerals and depression of quartz minerals. Both feldspar and

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 and power intensities prior to multistage feldspar flotation. Particularly, the quality of feldspar concentrates, the volume of removed slimes and the content of impurities were taken into account to reveal the impacts.
