Therefore, although Fe(III) effectively improved the flotation of spodumene, it was not beneficial for the flotation separation of spodumene from feldspar and quartz. When Ca(II), Mg(II), and Cu(II) were used as activators, the adsorption amounts of α-BDDA on spodumene were significantly higher than those on feldspar and quartz, which led to a higher recovery of spodumene.
