The surface of silicon was hydrophobic after HF treatment, allowing the enhanced recovery of silicon, and consequently, the separation of silicon and the silicate. Using flotation, LIU et al [17] determined that the recovered silicon powder (72.12% in purity) mainly contained elemental Si and low contents of Ca, Al, O, and C. Together with the ...
