摘要
采用十二胺作捕收剂，单宁酸作调整剂，可使硅灰石与透辉石有效分离，其原因在于单宁酸对透辉石具有选择性抑制作用。Ａｕｇｅｒ电子能谱研究表明，透辉石表面Ｃａ２ｐ的结合能比硅灰石更高。
An effective separation of wollastonite from diopside can be achieved using do decylamine as a collector and tannic acid as a modifying agent. This is due to the fact that tannic acid has a selective depressing effect on diopside. Auger energy spectrum study has shown that there is a higher binding energy of Ca 2p on the surface of wollastonite than on diopside, and it is easier for —OH in tannia acid and —COO - radical to combine with Ca 2+ on the surface of diopside.
