Low-grade magnesite ore is seriously polluting the environment with its waste stockpiles. Quartz is the main gangue mineral in magnesite, and the strong hydrophilicity of the two minerals makes flotation separation difficult. In this study, TIPA was added to the mill to enhance the flotation separation of magnesite and quartz.

Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O'Meara, 1939). (1979) reported that HF creates a large difference in the minerals' zeta potentials as the zeta …
