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
separation of quartz from feldspar . new condition for separation of orthoclase from quartz by flotation. Washing and high intensity magnetic separation (12 Ampere) afford to reduce the ironbearing impurities up to % Fe^sub 2^O^sub 3^, and the flotation is the best way for the separation of Kfeldspar from quartz by appropriate reagents for this purpose (HBr, amine).
Differential Flotation of Some Egyptian Feldspars . viability [2] [4] [5] It is now possible to free feldspar from all kinds of gangue minerals, eg mica, quartz and heavy minerals in addition to separation of both K and Na feldspars from each other [2][4] Cationic flotation of feldspar amine + HF in presence of NaCl was conducted by CengizDemir of Turkey in 2010 to separate both
For separation of Quartz from Feldspar absolutely best way is application of selective flotation (depends on quantity of Quartz and Feldspar you can use Amine (cationic) collector using HF as

Quartz can be floated from feldspar in diluted HF solutions simply by the aid of frothers. There is a high flotation separation selectivity between quartz and different types of feldspar. A feldspar concentrate of % at a recovery of gt;95% was produced. The results could be

Flotation Separation Of Feldspar From Quartz. removal of mica from feldspar for acidic minerals, were used in the flotation of feldspars in the thirties. In 1982, it was found that C 614 primary amine hydrochloride collectors were used for the flotation of feldspars in presence of HF or a

#0183;#32;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 23 (OMeara, 1939). (1979) reported that HF creates a large difference in the minerals zeta potentials as the zeta

Quartz and feldspar are both silicate minerals with a framelike structure, which are similar in physical and chemical properties, such as nonmagnetic and close in density. Currently, flotation is mainly used for separation. Although the hydrofluoric acid method can separate quartz and feldspar better, because of the serious pollution of the environment and equipment by HF, the current
