He found that the red pigment proved to be iron oxide, hematite; a yellow consisted of clay containing iron or yellow ochre; a blue color was a finely powdered glass; and a pale blue was a copper carbonate, probably azurite; green were malachite; black was charcoal or boneblack; gray, a limestone mixed with charcoal; and a quantity of pigment remaining in a paint pot used in the decoration, contained a mixture of hematite with limestone and clay.

Based on a brief analysis of the genesis of hematite, the authors hold that hematite in red granite was mostly produced under the condition of high oxygen fugacity.

本文對赤鐵礦的成因作了簡要分析欧美性色作爱视频，認(rèn)爲(wèi)紅色花崗巖中的赤鐵礦大多為高氧逸度條件下的產(chǎn)物。

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.

The result of studying is that the minerals of Fe in A layer clay-stone of kaolinite are hematite, goethite and siderite, but the most is hematite and goethite.

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.

根據(jù)紅外光譜和XPS測試結(jié)果可知，在弱酸性介質(zhì)中亚洲欧美日韩区中文字幕，活性硅酸膠體抑制劑中荷正電的膠團(tuán)H〓SiO〓及〓由于電性吸引而選擇性地覆蓋在荷負(fù)電的鈉輝石表面a和黄色网站，從而阻礙了陰離子捕收劑與表面Fe〓的配位作用，導(dǎo)致鈉輝石的浮游被抑制国产一级aⅴ无码免费；而赤鐵礦表面由于荷正電一级黄毛片4466网站，與礦漿中的H〓SiO〓、〓等硅酸膠團(tuán)存在著電性排斥作用日韩免费爱插摸视频，有利于赤鐵礦顆粒的穩(wěn)定分散欧美性站，所以赤鐵礦能夠被脂肪酸捕收劑吸附而選擇性上浮。

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.

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.

This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite欧美日韩亚洲二视区、hematite日韩性色一级A片、 SFCA、larnite亚洲精彩视频一区二区三区、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.
