Selective flotation separation of spodumene from feldspar

Jun 05, 2020 Fig. 2 shows that the effect of pH on the flotation recovery of spodumene and feldspar using individual collector at dosage of 4 × 10 −4 mol/L. When DS was used as a collector, the recovery of spodumene and feldspar at neutral pH range were high, reaching more than 60 %. Moreover, it can be seen that the recovery of spodumene and feldspar were relatively close throughout the studied pH

Selective flotation separation of spodumene from feldspar

Oct 01, 2020 Single-mineral 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.

Selective flotation separation of spodumene from feldspar

Apr 01, 2016 However, the ion activation has a poorly selective flotation of spodumene as the gangue minerals such as feldspar and quartz are activated simultaneously by metal ions. Fuerstenau and Rai have studied the anisotropic crystal chemistry of pegmatitic aluminosilicates with sodium oleate (Moon and Fuerstenau, 2003, Rai et al., 2011).

Developing Effective Separation of Feldspar and Quartz

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [ 9] in an acidic environment (pH = 2.1). It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [ 10 ].

Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed by amine at basic pH values.

Dressing of Quartz-Feldspar Ores on the Basis of Selective

The process of selective disintegration of hypergenically changed sand in ball and centrifugal mills is studied. The possibility is shown for its effective dressing by transforming feldspars into the finer products with quartz concentration in the coarser fractions. It is established that in grinding, the mechanical activation of surface intensifies flotation separation of the minerals mentioned.
