| 摘 要： | The floatabilities of single mineral samples of wollas-tonite and diopside have been studied with addition, of a cationic collector,dodecyoamine hydrochloride (DDA·HCl) , and,modifiers. A mixture oftwo minerals was successfully separated,when DDA·HCl and tannicacid (as depressant)were used together. The interaction between tannicacid and wollastonite and diopside in the pulp and the adsorption of tannicacid on the surface of the two minerals was studide with the help of ultra-violet (UV) spectroscopy and X-ray photoelectron spectroscopy (XPS) ,re-spectively.

| Abstract: | The floatabilities of single mineral samples of Tvollas-tonite and diopside have been studied with addition of a cationic collector , dodecylamine hydrochloride (DDA ?HC1) , and modifiers. A mixture of two minerals was successfully separated , when DDA ?HC1 and tannic acid (as depressant)were used together . The interaction between tannic acid and wollastonite and diopside in the pulp and the adsorption of tannic acid on the surface of the two minerals was sttidide with the help of ultra-violet (UV) spectroscopy and X-ray photoelectron spectroscopy (XPS) , re-spectively. |
