In such partial melting reactions, accessory phases that concentrated LREE like monazite occurred as residue phases, which resulted in extremely low LREE and P-2O-5 contents and elevated Sm/Nd ratios in the melts.

在部分熔融过程中，诸如独居石这样的富含轻稀土元素的副矿物以残留体的形式出现，不参与部分熔融，导致BH-2-3具有很低的LREE和P2O5含量及高达0.4122的Sm／Nd比值。

A soft, silvery-white, malleable, ductile, metallic rare-earth element, obtained chiefly from monazite and bastnaesite and used in glass manufacture and with other rare earths in carbon lights for movie and television studio lighting.

镧：一种质软、银白色、有延展性的、可塑性的稀有金属，主要是从独居石和氟碳铈矿中提取出来，用于玻璃工业及电影或电视摄影照明的碳棒灯中。

Monazite, rutile, phosphorus and yttrium ore, tantalum and niobium ore, zircon, ilmenite and exploitation of the reserves volume ranks first in the country, Yunfu pyrite is China's largest reserves of pyrite in the sulfur content of the highest in a large-scale mine.

独居石、金红石、磷钇矿、钽铌矿、锆英石、钛铁矿的储藏量和开采量均居全国首位，云浮硫铁矿是中国硫铁矿中储量最多、含硫量最高的一座大型矿山。

I can provide raw materials for the Division include: tantalum ore, niobium ore, tungsten ore, molybdenum ore, cobalt ore, nickel ore, monazite, zircon ore, chromium carbide, vanadium carbide and so on, the majority of imported raw materials.

我司可提供的原材料包括：钽矿、铌矿、钨矿、钼矿、钴矿、镍矿、独居石、锆矿砂、碳化铬、碳化钒等，大部分为进口原料。

Jiangmen boasts of rich mineral resources with 37 kinds of minable minerals, including limestone, silica sand, potassium feldspar, monazite, crystal, aquamarine , coal, tombarthite/rare earth, gold, silver, copper, iron, stannum and tungsten, among others.

矿产资源丰富，已探明可开采的有石灰石、硅砂、钾长石、独居石、水晶、绿柱石、煤、稀土及金、银、铜、铁、锡、钨等37种。

The hexagonal and monoclinic monazite CePO4 nanowires with a narrow range of diameter distribution and large aspect ratio were synthesized mildly through hydrothermal process at 150 ℃ using CeCl3·7H2O and H3PO4 as the raw materials. The crystal structure, micro-morphology, and photoluminescence of the nanowires were characterized by XRD, TEM, HRTEM, and UV spectrophotometer.

以铈盐和磷酸为前驱体，经水热合成获得了高长径比的具有六方晶型和单斜晶型独居石结构的CePO4纳米线，采用XRD、HRTEM、SEM和荧光光度计对其晶相组成、形貌及发光性能进行了表征。

Used for particle size sorting of 0.3 - 0.02 mm fine-grained iron, tin, tungsten, tantalum, niobium, gold, coal, monazite, rutile, Gao Yingshi, as well as the proportion of the poor have enough other metals, nonmetallic minerals by the Ministry of Metallurgy organization of scientific research, design, universities and factories, mines and other units were identified by that excellent performance of the device, the advanced sorting index to determine the mass-produced to promote the use.

用于选别粒度0.3--0.02毫米细粒的铁、锡、钨、钽、铌、金矿、煤矿、独居石、金红石、镐英石以及具有足够比重差的其他金属、非金属矿物，经冶金部组织有关科研，设计、高校和厂矿等单位进行鉴定通过，认为该设备性能优良，选别指标先进，确定成批生产推广使用。
