岩浆分异或不混溶作用形成的晚期含矿岩浆可以形成矿浆贯入型铁矿，更多的是侵入岩浆与地层发生交代反应形成的矽卡岩型铁矿。

The wolframite, scheelite, tantalum niobite and fine spar have uneven distribution in the raw ores. Relatively, the wolframite and scheelite have coarse embedded granularity, generally 0.8 ~ 0.04 mm. The tantalum niobite and fine spar have fine embedded granularity, generally 0.2 to 0.04 mm.

原矿中黑钨矿、白钨矿、钽铌铁矿、细晶石的嵌布粒度皆为不均匀嵌布，黑钨矿与白钨矿的嵌布粒度相对较粗，一般为0.8~0.04毫米，而钽铌铁矿及细晶石的嵌布粒度则很细，一般为0.2~0.04毫米。

However, due to its high-phosphorus iron ore oolitic hematite, phosphate ore has reached 0.3%-1.8%, much higher than the phosphorus content of iron ore industry must be 0.2 percent in the standard, coupled with transportation inconvenience that this has been sleeping underground mineral resources to be developed in the state.

但由于其铁矿为高磷鲕状赤铁矿，矿石的含磷达到了0.3％－1.8％，大大高于工业铁矿含磷量必须在0.2％的标准，加上交通运输不便，这一矿产资源一直沉睡地下而处于待开发状态。

Based on petrographical observations in red rutile ore, PI is possibly the transitional phase and complete reactants are Ath + Phi.

红色金红石矿中金红石成分均匀，未见有钛铁矿的出溶现象，黑色金红石矿中金红石存在明显的厚度可大于2μm钛铁矿出溶叶片。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.

本研究在前期工作基础上，针对已发现的硫复铁矿富集区选择典型柱状样6根(深约1.5-2.5m，长柱样；B436、B437、B439、B459、B483、B484)，同时于扬子浅滩前缘新获取柱状样4根(深约0.3-0.5m，短柱样；ST9、ST13、ST15、ST23)，进行了U系测年，粒度分析、磁性测量、X—射线衍射分析、微体古生物鉴定分析、粘土矿物和化学元素含量测试，试图揭示东海外陆架浅部地层结构、揭露硫复铁矿在地层中的分布规律及成因机制，从而探讨该区晚更新世以来海平面波动模式及其控制下的地层发育。

The flotabilty of titanaugite and ilmenite and the effects of different size fractions of titanaugite on the flotability of ilmenite were studied by flotation tests and DLVO theoretical calculations.

摘 要：采用浮选实验和DLVO理论计算，研究钛辉石和钛铁矿各自的可浮性以及各粒级钛辉石对钛铁矿可浮性的影响规律及机理。

Infrared spectroscopic analysis shows that the water glass is chemically adsorbed on the surface of titanaugite but this reaction is weaker between the water glass and ilmenite; hetero-coagulation will occur easily under weak acidic condition because of the opposite surface charge of ilmenite and titanaugite.

红外光谱分析表明：水玻璃与钛辉石发生化学吸附，而在钛铁矿表面吸附较弱；在弱酸性条件下，由于钛铁矿与钛辉石表面带异相电荷而容易发生异相凝聚，添加水玻璃使二者表面电位均显负电性，矿粒间静电斥力迅速增大，从而减弱矿粒间的异相凝聚。

Disposal on methyl orange solution by two kinds of nanometer sized iron oxyhydroxides:α-FeOOH and β-FeOOH in visible light showed that methyl orange solution decolored by 90% by FeOOH/H2O2 system.And phenyl in methyl orange molec...

用2种纳米氧氢氧化铁针铁矿，正方纤铁矿处理偶氮染料分子甲基橙溶液，在自然光下，FeOOH/H2O2体系能使甲基橙溶液脱色率达90%，并且能将甲基橙分子中的苯环部分打开。

The sulphur in E'Kou Ironstone comes from sulphide (pyrite,pyrrhotite,chalcopyrite, binarite)and sporadically distributes in the ore or veined parallels/intercalates banded ferrosilicon formations.

峨口铁矿矿石中的硫来源于硫化物(黄铁矿、磁黄铁矿、黄铜矿、白铁矿)，呈星点状，散布于矿石中或呈脉体平行或穿切硅铁建造条带。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
