Developing Effective Separation of Feldspar and Quartz

The effect of hydrofluoric acid (HF) pretreatment on flotation of feldspar and quartz using dodecylamine (DDA) as collector was investigated by micro-flotation, zeta potential, pyrene fluorescence spectroscopy, attenuated total reflection flourier transformed infrared spectroscopy (ATR-FTIR), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and bench scale flotation.

Recovery Slime Waste from Feldspar Flotation Plant at

Study on fine feldspar flotation, which is for removing quartz from feldspar, showed that the optimum condition of 20% solids must be adjusted to pH 2 by hydrofluoric acid (HF), using A-

Differential Flotation of Some Egyptian Feldspars for

The flotation behavior of feldspars is essentially determined by their surface condition and thus by the extent of hydrolytic decomposition of feldspar surfaces [6]. The cationic-type collectors, which are most satisfactory for acidic minerals, were used in the flotation of feldspars in the thirties. In 1982, it was found that C 6-14 primary

(PDF) Separation of Feldspar from Quartz: Mechanism of

The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and 45–75 μm) are investigated in single mineral micro-flotation tests.

Selective flotation separation of spodumene from feldspar

Apr 01, 2016· The flotation separation of spodumene from other complex aluminosilicate minerals such as feldspar and mica, is problematic, due to their same active Al site for interaction with anionic collectors (Rai et al., 2011). In practice, the general method to accomplish effective spodumene flotation is to add amount of depressants associated with

AP-42 Background Document for Section 11.27 Feldspar

To finish the flotation process, the discharge from the second flotation step is dewatered again, and a cationic amine is used for collection as the feldspar is floated away from quartz in an environment of hydrofluoric acid (pH of 2.5 to 3.0).

Review of flotation of feldspar: Mineral Processing and

A commercial feldspar product usually contains more than one feldspar mineral, and flotation conditions for the separation of individual feldspar minerals have been developed to produce individual feldspar minerals for specific applications. Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine

Feldspar Beneficiation Process Magnetic & Flotation

Flotation separation of potash feldspar and albite The separation of potash feldspar (orthoclase and microcline) and albite is a challenging issue because they are mostly mixed in feldspar deposits and these minerals have similar chemical structures and similar physical chemistry properties.

feldspar extraction, feldspar processing, process of

Feldspar is a kind of silicate minerals which contains calcium, sodium and potassium, there are many categories of Feldspar including albite, anorthite, etc. Feldspar mining process mainly applying flotation process, and Feldspar mining machines mainly including jaw crusher, ball mill, spiral chute, and concentrating table, etc.
