我国利用矿石制作中药已有几千年的悠久历史，这类药物除天然矿物、岩石和化石外，还

This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.

该类矿床以矿石中含有大量的铁氧化物且伴有很强的区域性钠质蚀变为特征，可以产于元古代克拉通内或新生代大陆边缘岛弧环境，其周围具火成岩或含蒸发盐层，时空上与之有关的侵入岩为磁铁矿系列花岗岩，矿化主要产于近区域主断裂的羽状次级断裂中。

Bioleaching may require added phosphorus and nitrogen if these are limiting in the ore materials, and the same process can be used to solubilize uranium.

如果在矿石中氮和磷不足，生物萃取则需要加入这些营养素，并且这一过程还被用来提取铀。

A methodology is presented for the spatialization and regularization of geological data in developing a volume visualization system of mineral deposits.

系统地论述了矿床体视化过程中由原始采样数据生成空间规则体数据的实现方法，分析了能够形成地矿体空间体数据的主要插值方法的优缺点，在充分考虑矿石品位的空间相关性和变异性的前提下，利用Shepard法实现了空间体数据的生成

We can see copper-bearing asphalt amygdaloidales in the basalt lava and stockwork of native copper in the carbon-rich tuff. There area so much carbon in the ores that people only can see the native copper aggregate after splitting and polishing the ores.

最近，在该熔岩层上下的凝灰岩中鉴别出难识别矿化类型，即与沥青和有机质碳紧密伴生的富铜矿石，甚至在气孔状熔岩中发现呈杏仁体含铜沥青，因而可能构成大规模矿化。

Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.

矿体产于红岩寺—黑山复式向斜南翼金井河—胡家沟次级背斜南翼近轴部断裂中，赋矿岩石为泥盆系青石垭组中上部白云质岩，其空间展布明显受背斜陡倾南翼近轴部的层间断裂-裂隙带构造控制，矿石主要有团块状和网脉状，其后生成矿现象非常明显。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

It occurs stratigraphically within metamorphosed Archean sedimentary rocks and has many characteristics of syngenetic stratiform deposit:very regular shape of ore bodies, homogeneous distribution of gold in ore formation, large reserve and close association with beded barite.

赫姆洛金矿在太古代晚期地层中沿层产出，矿体形状规则、规模巨大，矿石品位均匀，具有同生层状矿床的特征。

We studied some new colour reactions for the first time. Amino-Gacid chlorophosphonazo, sulphonic acid amide chlorophosphonazo and phippuric acid chlorophosphonazo were used to establish flow injection spectrophotometric methods of Pd in ores.

我们首次探索了一些前人未研究过的新显色体系，使用氨基G酸偶氮氯膦，磺胺偶氮氯膦，对马尿酸偶氮氯膦建立了测定矿石中Pd的流动注射分光光度法。

Bioleaching, by means of natural populations of Thiobacillus ferrooxidans and related Thiobacilli, for example, allows recovery of up to 70% of the copper in low-grade ores.

生物萃取，例如应用天然的氧化亚铁硫杆菌菌群和相关的硫杆菌，使低品级的矿石中铜的收率达到70％。
