Therefore, reverse flotation separation of magnesite from quartz in the presence of DDA as a collector can cause a large amount of magnesite to float together with silicon-containing gangue minerals, which can lead to reduced recovery of magnesite in the concentrate. Therefore, the selectivity of DDA between magnesite and quartz still needs …
