Froth flotation of mixed feldspar

Froth flotation was used to separate feldspar from micas, ironbearing minerals and quartz using cationic, anionic and acid flotation respectively. Evaluation of the separation was done by using data from yield of feldspar, Xray fluorescence and cone firing test. The feldspar yield was used to evaluate the process efficiency.

Quartz

Benchscale flotation experiments using cationic collectors GTAP and Flotigam V4343 and using HF and H 7 SO 4 as modifiers were employed to separate feldspar from quartz and to remove part of the titanium impurities. The best results were achieved with a combination of highintensity wet magnetic separation and flotation.

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.

Effects of Ultrasound on Desliming Prior to Feldspar

In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency and power intensities prior to multistage feldspar flotation. Particularly, the quality of feldspar concentrates, the volume of removed slimes and the content of impurities were taken into account to reveal the impacts.

froth floatation separation quartz from feldspar

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 2–3 (O''Meara, 1939). (1979) reported that HF creates a large difference in the minerals'' zeta potentials as the zeta
