At a XG dosage of 8 mg/L, the recovery and grade of quartz in a flotation tailing reach approximately 90 %, where the recovery and grade of apatite are only around 10 %. This experimental outcome suggests that the use of DDALA collector, in conjunction with XG depressant, effectively achieves the reverse flotation separation of apatite from quartz.

When quartz is crushed under water, the broken bonds at the quartz surface react with water molecules to form a surface silicic acid. The ionization of surface silicic acid gives rise to the change of the surface charge of quartz [31]. Thus control of pH is important in the reverse flotation, due to the extent of surface ionization.
