FLOTATION SEPARATION OF FELDSPAR
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 A major proportion of feldspar ores contain both Nafeldspar (Albite) and Kfeldspar (microcline or orthoclase) in the same matrix, usually in quantities of about 3–5% Na 2 O and K 2 O Despite their identical crystal structures and physicochemical properties, flotation appears to be the only plausible method of separating these mineralsFlotation separation of Nafeldspar from Kfeldspar by 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 testsSelective flotation separation of spodumene from

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 mineralsAn 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 for activation with hydrofluoric acidUSA Flotation separation of feldspar Separation of feldspar from quartz by flotation Lawrence J Herber Department of Physics and Earth Sciences, California State Polytechnic College, Pomona, California 91766Separation of feldspar from quartz by flotation
Selective Flotation Separation of Feldspar in Non
In the conventional flotation separation of feldsparquartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector The bulk of amine collectors used in current feldspar The problem in feldspar flotation is to recover slime free granular products, all minus 20 mesh, usually with not over 10% finer than 200 mesh Flotation under these conditions is critical and pulps are abrasive as well as corrosive Action of the feldspar Feldspar Beneficiation Flotation ProcessTraditionally, there are two main flotation separation processes to remove quartz from feldspar The first one is hydrofluoric acid flotation, which uses hydrofluoric acid (HF) or fluoride (NaF) as a feldspar Developing Effective Separation of Feldspar and
