-
TDM is an effective collector for sphalerite with less CuSO4 and without frother.
-
TDM chemisorbs on the minerals surface.
-
Adsorption modes of TDM on mineral surfaces are obtained by first-principle study.
-
Absorption energies of TDM on ZnS (110) and FeS2 (100) are ⿿394.78, ⿿219.33 kJ/mol.
-
Reactions happen between S 3p orbital of TDM and 3d of Zn/Fe orbital of minerals.
