The disseminated chromite characteristically forms rudely octahedral crystals , 0 . 05 - 0 . 15mm in size 浸染状铬铁矿特征性地形成大致的八面体晶体0 005 0 15毫米大小。
Abstract : it introduces the reaction principle of oxidative roasting of chromite with few calcic additives , also describs its technical essentials and process control 文摘:介绍了铬铁矿少钙氧化焙烧的反应原理、工业应用及应用过程中的技术要点和过程控制。
This product combines excellent micro structural flexibility with very good coat ability because of dead burned magnesia / low chromite / hercynite combination 由于重烧镁砂和低铬铁矿/铁铝尖晶石的组合，该产品结合了优良的微结构弹性和良好的造窑皮能力的优点。
Cataclastic texture which came from brittle deformation made the jadeite quality bed , but the mylonitic texture which resulted from ductile deformation made the jadeite quality good 在强大剪切应力和钠质流体的共同作用下，铬铁矿的淡化作用是形成绿色的主要原因。
Difficultly starts an undertaking after several years repeated difficulties , the scale grows strong unceasingly , at the same time thanks the general customers the vigorously support and the deep affection , develops successively develops the product : the cupric sulfide 、 the froth powdered iron 、 one 、 two time return to original state the powdered iron 、 the chromite 、 the pyrite 、 not the rusty powdered iron 、 the refinery coke 、 the wollastonite ( silicon ash cotton and kapok ) and so on the series powder body material 经过几年风风雨雨的艰苦创业，规模不断发展壮大，同时感谢广大客户的大力支持和厚爱，先后开发研制出产品：硫化铜、泡沫铁粉、一、二次还原铁粉、铬铁矿、硫铁矿、不生锈铁粉、石油焦、硅灰石（硅灰棉）等系列粉体材料。
For example , a batch of large and medium - sized key projects such as the yamzhog yumco pump storage power station and the norbusa chromite mine in shannan are put under strict supervision and management in accordance with the law on environmental protection ; the garbage dump located close to the lhasa river was moved to another place to minimize water pollution , and polluted water treatment centers were set up 为保护生态环境，环境保护部门采取了一系列措施，如对正在兴建的羊卓雍湖电站、山南罗布萨铬铁矿等一批大中型重点工程，严格依照环境保护法进行监督和管理；搬迁距拉萨河不远的垃圾场，以减轻对拉萨河的污染；建立污水处理场等。
Sapphire from shandon and hainan commonly have the reaction border , we found out this reaction border enriched with fe , mg , and k by testing its components ; we also studied the inclusion in the sapphire , and found many kc1 crystal grain with variety of size , a melt inclusion enriched with k , si , is also found , this may suggest an assimilationary - magmatic course ; besides that , another minerl inclusions such as enstenite , magnetite , chromite , zircon are also found 3 、观察到了山东、海南蓝宝石普遍存在的反应边，并测试了反应边的成分，证实其以富fe ， mg ，和k为特征；研究了蓝宝石里面的包体，发现蓝宝石里面存在着大小不等的kcl的结晶颗粒，还发现了富k富si的熔浆包裹体，说明其形成过程中有同化混染的贡献；此外还发现了斜方辉石，磁铁矿，铬铁矿，锆石的包体矿物。
The pouring tests of the ladder foam sample were made in silica sand , chromite sand and zircon sand the results show that zircon sand and chromite sand have the better chilling effect , and the structure of the aluminum alloy is finer , the hardness and strength has large improvement , subsequently the investigation provides the reference for manufacturing aluminum alloy thin thickness mold with excellent quality 结果表明，锆英砂和铬铁矿砂具有较好的激冷效果，得到的铝合金铸件组织细小，强度、硬度有较大的提高，为薄壁随型、质量优异的铝合金消失模模具制造提供了技术依据。
