  • Review of flotation of feldspar: Mineral Processing and

    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.

  • Selective flotation separation of spodumene from feldspar

    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

  • Feldspar Beneficiation & Flotation Process

    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

  • Selective Flotation Separation of Feldspar in Non Fluoride

    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

  • Amine–oleate interactions in feldspar flotation

    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

  • Processing Spodumene by Froth Flotation for Lithium

    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 Reagents Mineral Processing & Metallurgy

    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.

  • Two stage flotation of sodium feldspar from laboratory

    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

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
