| Abstract: | The depression mechanisms of tannin on the diopside surface have been studied by the use of Infrared spectroscopy (IR) ,simulated pulp and mixed solution tests , It is found that the first order hydroxy complexes of calcium are able to interact with tannin, and to form chemical complexes. The functional groups in tannin molecules participating in the chemical complexation are the hydroxyl groups,and carboxyl groups derived from the hydrolysis of hydroxyl groups. |
