Traditionally, there are two main flotation separation processes to remove quartz from feldspar. The first one is hydrofluoric acid flotation, which uses hydrofluoric acid
In the separation of finely divided feldspar and quartz, the step of floating off the fine feldspar by a cationic reagent, yielding long chain cations containing from twelve to nineteen carbon...
Froth flotation of mixed feldspar. Froth flotation was used to separate feldspar from micas, ironbearing minerals and quartz using cationic, anionic and acid flotation respectively. Evaluation of the separation was done by using data from yield of feldspar, Xray fluorescence and cone firing test.
#0183;#32;FLOTATION SEPARATION OF FELDSPAR . United States Patent . Abstract: An improved process for separating feldspars from feldspathic ores by means of froth flotation wherein a combination of a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate is used as a flotation reagent, eliminating the necessity
It has been found that feldspars can be separated efficiently from feldspathic ores and minerals by means of froth flotation when a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate are used in conjunction as flotation reagents in a flotation medium made acidic with sulfuric acid, without the necessity for using hydrofluoric acid.
Beryllium Extraction Process Flowsheet Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product.
Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = ).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a highquality quartz [].However, there is a large amount of chemical activator (HF or NaF) in the flotation system, as
applying conventional concentration techniques, magnetic separation and flotation [5, 6]. Several studies were conducted to improve feldspars specifications to meet the requirement of
#0183;#32;Singlemineral flotation results showed that using 30 mg/L SA allowed the separation of spodumene from feldspar at pH 6, although there was a strong pH dependence. Zeta potential measurements and FTIR analysis showed that SA and DDA can adsorb onto both minerals.
#0183;#32;Under the same dosage of reagents and pH conditions, the mixed collector NaOL/DS was more effective for the flotation separation of spodumene and feldspar, compared to single collector NaOL and DS. In the case of using a mixed collector NaOL/DS, the flotation recovery of spodumene was above 90 % and that of feldspar was approximately 28 % during single mineral flotation tests.
#0183;#32;The general circuit for commercial separation of feldspar consists of three sequential stages of flotation, all of which are carried out in an acid medium. Usually, before flotation, the feed is deslimed, removing any fine clay minerals present. In the first flotation stage,

Cationic flotation of feldspar (amine + HF) in presence of NaCl was conducted by CengizDemir of Turkey in 2010 to separate both Na and Kfeldspar. NaCl addition controls amine adsorption on sodium feldspar through adsorption of Na+ ions onto the mineral surface.
NaFeldspar, KFeldspar, Flotation, Sand Separation, Effect of pH . T. R. Boulos et al. 436 1. Introduction Feldspars are indispensable raw materials for many industries, such as ceramics, glass and fillers for plastics production.
