By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

From the results of IR and XPS spectrocopy. The cationic sol components H〓SiO〓 and 〓 of the solution trend to adsorp on the surface of electronegative aegirine because of electrostatic acctraction each other, and interrupted the collector's reaction with Fe〓 on the surface. Hence the flotation of aegirine was decreased, on the other hand, there is electrostatic repulsion between the surface of hematite and the cationic sol H〓SiO〓.〓, Which has advantage to dispersion of hematite particles, therefore, the hematite flotation is achieved sucessfully with anionic collector.

根据红外光谱和XPS测试结果可知，在弱酸性介质中，活性硅酸胶体抑制剂中荷正电的胶团H〓SiO〓及〓由于电性吸引而选择性地覆盖在荷负电的钠辉石表面，从而阻碍了阴离子捕收剂与表面Fe〓的配位作用，导致钠辉石的浮游被抑制；而赤铁矿表面由于荷正电，与矿浆中的H〓SiO〓、〓等硅酸胶团存在着电性排斥作用，有利于赤铁矿颗粒的稳定分散，所以赤铁矿能够被脂肪酸捕收剂吸附而选择性上浮。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.
