The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.

研究结果表明：内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%，体积分数)的氧化性气氛中焙烧强度最大，氧含量过高或过低都会影响Fe2O3的再结晶，使球团强度降低；在氧化性气氛中焙烧含碳赤铁矿球团时，原生赤铁矿先还原为磁铁矿，磁铁矿再氧化成活性较高的次生赤铁矿，提高了赤铁矿焙烧固结性能和球团强度。

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.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。

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。
