When pH=2, quartz is close to the zero electric point, while feldspar generally has a zero electric point pH=1.4~1.7. Under the activation of fluoride ions, the surface negative potential is enhanced, and the quartz surface is basically not charged. Amine cations are first adsorbed on the feldspar surface, making the surface hydrophobic.

Such mica minerals can be sorted by magnetic separation. Tests have shown that the mica content in the finished sand is greatly reduced after magnetic separation to remove mica. It can be controlled within 2%, which meets the sand standard, and the concrete mixing performance produced by de-mica machine-made sand is better.
