菱铁矿

Under supergene process influencing, kaolinites invered dickites, siderite were been ferritization, part of carbonate mineral have been dissoluted producing calcite.

在表生作用的影响下，高岭石向地开石转化，菱铁矿褐铁矿化，部分碳酸盐矿物溶解生成方解石。

Moreover, the ignition loss is relatively high. Analyses for XRD show that the main mineral components of gangue are kaolinite, mica, spathic iron, iron pyrites, rutile, bischofite, quartz and calcite.

XRD结果表明：煤矸石主要矿物成分为高岭石、云母、菱铁矿、黄铁矿、金红石、水氯镁石、石英以及方解石等。

"It occurs rarely as a free metal, occasionally in natural alloys, and in hundreds of minerals and ores, including hematite, magnetite , limonite, and siderite."

地壳中游离铁很少见，而通常存在于合金及数百种矿物中，包括赤铁矿、磁铁矿、褐铁矿和菱铁矿。

"It occurs rarely as a free metal, occasionally in natural alloys, and in hundreds of minerals and ore s, including hematite, magnetite, limonite, and siderite."

地壳中游离铁很少见，而通常存在于合金及数百种矿物中，包括赤铁矿、磁铁矿、褐铁矿和菱铁矿。

Advantages such as high production ability fast reaction velocity and low exhaustion are also proved in research.So it is one of the most advanced technology of hematite、siderite and limonite magnetizing roasting.

该工艺具有单位体积产能高，反应速度快，能耗低等优点，是赤铁矿、褐铁矿、菱铁矿磁化焙烧的先进工艺。

They focused on two minerals, magnetite and siderite, that can provide a bellwether of the CO2 concentrations in the atmosphere.

他们重点分析了两种矿物：磁铁矿和菱铁矿，这两种矿物可以为大气中的二氧化碳浓度提供征兆。

Too much CO2, and magnetite can't form, whereas the opposite is true for siderite.

如果大气中存在的二氧化碳太多，磁铁矿则无法形成；如果大气中存在的二氧化碳太少，菱铁矿则无法形成。

The reaction mechanism of producing H_2 by siderite/kaolinite mixed minerals under flowing nitrogen is discussed.

文中探讨了菱铁矿/高岭土混合矿物在N_2气氛下产生H_2的反应机理。

The early mineralization is related to sedimentation, which resulted in the formation of the siderite ore-body and some pyrite orebodies.

作者在综合分析该矿田的地质－地球化学特征的基础上，认为新桥矿田具有二期成矿作用的特点早期沉积成矿作用形成菱铁矿矿体和不具有工业意义的黄铁矿层。

Calcite siderite barite and others don't contain gold.

方解石、菱铁矿、重晶石等不含金。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
