Selective flotation of K-feldspar from Na-feldspar in ...

2019-10-1 · The selective fluorine activation of the feldspar surface by HF or similar (i.e. NaF + acid) is generally understood to be the reason for the preferential amine adsorption onto feldspar, as the amine ion cannot sufficiently adsorb on the feldspar surface by itself to promote the flotation of feldspar in the acidic medium (Shimoiizaka et al., 1976).

2020-6-5 · 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 ...
