Pure silicalite only exposed at surface is silica-bearing rocks of protore beds experiencing extreme oxidation at surface as additional production while generating oxidized manganese ores

纯硅质岩仅见于地表，是含硅质的矿胚层岩石，在地表经强烈氧化作用形成氧化锰矿石同时产生的&副产品&。

The method of processing of the gold-containing ores provides for the ore excavation at the mining works, its stage-by-stage ragging in the grinders with the check screening, separation of the ground ore by the sizes, separation from the ground classified ore of its sub-quality part and the barren rock.

含金矿石的处理方法决定了采矿工作中开采矿物的方式，其分阶段磨矿包括在研磨装置中检查筛选矿石、然后按照研磨矿石的粒度大小进行分离，将研磨分类矿石的低品位矿石与贫矿分离出来。

The method has been applied to the determination of trace Th in REE and U contained ores with satisfactory results

方法已用于测定稀土和铀存在下的矿石管理样中的微量钍，结果与原结果相符

The streaky and banded structures in the ores were resulted from the remobilization of solid-state mechanical transfer in plastic deformation of "soft" sulfides.

各矿化体目前的产状和空间关系主要受后期构造变形控制，矿化体的初始空间展布需要甄别和恢复。

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。

More sophisticated recent methods, such as spectrochemical analysis, are not suited to assaying precious metal ores because the samples of the inhomogeneous ore that must be used are larger than the instruments can handle.

近代较复杂的方法不适合分析贵金属矿，因为那些必需使用的杂质矿样品比工具大得多，不能操作。
