Selective flotation separation of spodumene from

01-10-2020  These results indicate that a moderate amount of SA can effectively depress feldspar and has a minimal effect on the adsorption of DDA on the surfaces of spodumene. Therefore, the optimum reagent scheme for the flotation separation of spodumene from feldspar in the subsequent flotation tests was SA (30 mg/L) + DDA (0.2 mM).
