Raymond Red Star machines widely used in production of barite, calcite, potash feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, swelling earth, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc. Mohs hardness is not greater than 9.3 and humidity below 6% of non-inflammable mineral, chemical and construction industries more than 280 kinds of materials of high fine flour processing, particle size 80-325 mesh finished products within the scope of arbitrary regulation, part of the material up to 600 mesh.

红星机器生产的雷蒙磨广泛适用于重晶石、方解石、钾长石、滑石、大理石、石灰石、白云石、莹石、石灰、活性白土、活性炭、膨润土、高岭土、水泥、磷矿石、石膏、玻璃、保温材料等莫氏硬度不大于9.3级，湿度在6%以下的非易燃易爆的矿产、化工、建筑等行业280多种物料的高细制粉加工，成品粒度80—325目范围内任意调节，部分物料最高可达600目。

The most important barium-bearing mineral in this district is barite, but barium is also present in psilomelane, gillespite and other minerals.

本矿区最重要的含钡矿物是重晶石，但钡也出现在钡硬锰矿、硅铁钡石等矿物中。

Calcite siderite barite and others don't contain gold.

方解石、菱铁矿、重晶石等不含金。

The alterations are mainly silicification and sericitizatio...

蚀变作用以硅化和绢云母化为主，伴生重晶石化和蒙脱石化。

Non-metallic minerals are mainly limestone, dolomite, quartz sandstone, sillimanite, fire-resistant clay, broken mica, talc, serpentine, quartz, feldspar, rock wool with diabase, with finishes of granite, marble, heavy Spar, and so on.

非金属矿产主要有石灰岩、白云岩、石英砂岩、硅线石、耐火粘土、碎云母、滑石、蛇纹石、石英、长石、岩棉用辉绿岩、饰面用花岗岩、大理岩、重晶石等。

The metallic minerals in the ore occur as sulfides. Galena and sphalerite coexist with pyrite and barite.

矿石中金属矿物以硫化物形式存在，方铅矿、闪锌矿与黄铁矿、重晶石等共生。

More than 70 witherite and barite deposits occurred in the southern Qinling Mountains ,and constituted a unique large-scale Ba metallogenic belt in the world.

在南秦岭一带的下寒武统硅岩建造中，既存在一大批重晶石矿床，又发育大量毒重石矿床，构成世界上极为罕见的大型钡成矿带。

Bastnaesite crystal about 12×20 mm in size collected from a pegmatitic aegirine augitebarite-bastnaesite vein of the Maoniuping rare earth deposit, Mianning County, Sichuan Province,has been analyzed for La, Ce, Pr and Nd by synchronous radiative X-ray fluorescence technics at the National BEPC Laboratory.

对采自四川省冕宁县牦牛坪稀土矿床中伟晶状霓辉石－重晶石－氟碳铈矿脉的一个氟碳铈矿晶体（约12×12mm）在BEPC国家实验室采用同步辐射X萤光技术分析了La、Ce、Pr和Nd。

Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics.

研究结果表明，该区钒矿主要产出于青石峡－余家台倒转复式向斜两翼下寒武统水沟口组下岩段硅质岩夹泥岩的泥岩中，矿体产状与地层产状基本一致；钒矿床中所有岩石都含有较高的SiO2，硅质岩以隐晶质石英和玉髓为主，有沉积成因重晶石；V与Cr、U、Ba相关性好；稀土元素球粒陨石标准化模式具有或正或负的Ce异常和明显的Eu正异常、向右倾的图形。

Common fillers are various silicates, carbonates and sulfates such as clay, limestone, calcium carbonate, magnesium carbonate, barytes, etc. Water is added to produce a filler that spreads easily when applied and drys into a hard mass.

普通填料有各种硅酸盐，碳酸盐和硫酸盐，如粘土，石灰石，碳酸钙，碳酸镁，重晶石等水是增加生产填料容易传播和应用时drys变成硬肿块。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
