Compared with quartz, the surface electronegativity of apatite is weaker, while the polar group charges of HDMEA and DDA are almost the same, so the large polar group size might explain that HDMEA showed the weaker collection effect on the apatite than DDA. Consequently, the HDMEA exhibited better separation behavior for quartz and apatite.

Separation and Purification Technology
The purification of high-purity quartz is crucial in several application domains [4]. However, due to the fact that today's high-grade quartz resources are increasingly depleted, it should be separated and purified from other low-grade quartz mineral resources. The best choice is the quartz sand mineral, which is available and commonly used.
