Selective flotation separation of spodumene from …
Obviously, neither anionic collector NaOL nor nonionic collector DS can realize flotation separation of spodumene and feldspar successfully, however, the mixed collector maybe provide a good approach. Fig. 3 shows the effect of NaOL: DS molar ratio on the flotation recovery of spodumene and feldspar.
Selective flotation separation of spodumene from …
As shown in Fig. 4, the SA dosage has a considerable effect on the separation of spodumene and feldspar. As the SA concentration increased, the feldspar flotation was efficiently depressed, and the recovery dropped to less than 15%, although the flotation of spodumene was maintained at more than 79% until the SA dosage exceeded 50 mg/L.
