The purification methods of ten main single minerals in Dajishan Tungsten Mine is introduced,they arewolframite,scheelite,chalcopyrite,pyrite,galena,sphalerite,pyrrhotine,magnetite,arsenopyrite and cassiterite.
介绍了大吉山钨矿主要十种单矿物(黑钨矿、白钨矿、黄铜矿、黄铁矿、方铅矿、闪锌矿、磁黄铁矿、磁铁矿、毒砂、锡石等)的提纯方法。
On the basis of the speed difference of transition of the mineral particles of different density on the small arc special shaking inclined plane, separating minerals is made at a density, as a result, monominerals could be extracted.
该仪器利用不同密度的矿粒在作特殊振动的狭小弧形斜面上移动的速度差异，实现矿物按密度分选、提取单矿物。
This paper discusses the theoretical base that monominerals such as quartz and sphalerite can be used as a target of Rb-Sr dating contour determination It introduces the process of sample collection and preparation, analyses the determination result and presents the formation cause of Dulong tin and zinc deposit at last.
讨论了采用石英、闪锌矿等单矿物作为Rb-Sr等时线法测定对象的理论依据,介绍了样品的采集制备过程,分析了测定结果,提出了都龙锡锌矿床的成因模式。
Researches show that the distribution of the trace elementsin monominerals in Fankou Pb-Zn deposit is strictly controlled by thetypes of minerals.
研究表明:微量元素在单矿物中的分配严格受矿物类型控制;微量元素组合与元素性质和成矿作用有关;单矿物中某些元素对比值可定量地说明矿体形成深度、成矿压力和成矿温度,以及判定矿床成因。
SEM/EDX is applied to investigate mineral compositions of the inpidual particles in the inhalable particulate matter(PM10) collected in Lanzhou urban area(Dongfanghong square) and suburb(Yuzhong County) in the winter,2005.
为研究兰州市2005年冬季大气可吸入颗粒物(PM10)中单颗粒的矿物组成,用能谱扫描电镜识别和统计了兰州市区(东方红广场)和郊区(榆中县)两个采样点的单矿物颗粒。
