The depression behavior and mechanism of tragacanth
2021-8-1 · The depression effect was investigated by single mineral and mixed minerals flotations, and TG’s adsorption mechanism was studied by XPS analysis and ToF-SIMS measurement. Flotation test results showed that TG had strong depression effect on chalcopyrite flotation but hardly affect molybdenite flotation at pH 3–8.
