An alternative process which exhibited effective separation of quartz and feldspar while recycling the tailwater from the flotation was proposed. X-ray diffraction (XRD) spectra of the purified ...
The role of soluble starch in the flotation separation of feldspar from quartz was revealed through the single mineral flotation test, potentiodynamic test and absorption measurement. The results showed that soluble starch inhibited the flotation of feldspar and quartz when dodecylamine (DDA) and sodium dodecyl sulfonate (SDS) were used as mixed …
Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were investigated in the presence of K + ion as counter ion. In order to identify the role of K + ions on the selective …
It has been found that the vibration significantly helped to eliminate the particle aggregation and thus to improve the separation. At the optimized parameter values, the DVHGMS could purify the potash feldspar from the Fe2O3 grade of 0.191% in feed to 0.035% in non-magnetic product, while the mass weight of feldspar was 92.35%.
Quartz is often symbiotic with feldspar silicate minerals, which is difficult to separate and purify because of their similar physical and chemical properties.
