Mortar specimens were prepared, in which finely pulverized zirconite which is inactive under the reaction condition of this experiment was used to replace ground carbonatite or ground granulated blast-furnace slag isometrically, so as to investigate the contribution of each material to the performance of the products.

本文采用无活性的锆美石分别等体积替代碱激发碳酸盐矿-矿渣胶凝材料中的碳酸盐矿和矿渣，考察此三个体系的强度变化以及通过DTA分析存在协同效应的可能性，进而通过净浆硬化体的孔溶液成分分析研究复合作用机理。

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。

The letter asked.there are very large contracts already let to Raibus, the locally owned business development company, to perform almost all janitorial, security, catering and other support functions.the technocrats we need cost money to bring to Papua New Guinea, and we only bring as many as the project needs at this crucial stage of the construction and development schedule.

镍矿把一个非常大的合同已经承包给当地的一家企业发展公司，以执行几乎所有的门卫、保安、餐饮和其他后勤功能。关于技术骨干，镍矿只会在这个项目的建设和发展的关键阶段才引进，需要时间。

After the culture under the mineralization fluid condition in about 1 wk, the compact circular group appeared in the intercellular space, simultaneously cell multiplication ability reduced compared with the conventional culture; The sodium alizarinsulfonate dyeing showed the compact and circular lightproof briquetting brown laminated shape in the mineralizd intercellular spac, I collagen immunity group dyeing was strongly positive in the coloring region.

在矿化液条件下培养1周左右，细胞间出现了致密圆形团，同时细胞的增殖能力较常规培养有所降低；茜素红染色结果显示矿化细胞间出现的致密的、圆形不透光团块呈现片状的棕染，着色区域， I型胶原的免疫组化染色强阳性。

Comparison studies on mineralization characteristics of the 414 ore deposit with Limu orefield indicate some similarities in mineralization ,which were resulted from the similarities in evolution of the rare metal-bearing mag-matic rocks.

江西414矿和广酉栗木矿是我国目前钮的主要原料基地。在成固类型上它们同属稀有金属花岗岩型矿床，成矿元素除袒之外，还伴生锯、锡或埋。

On the farm where I grew up, once a week I watched a small airplane appear, coming from the direction of the city. It descended over the ridge into the bush on to the airstrip of the Mandora Mine, a Lonrho mine.

在我长大的农场，每周我能看见一次小飞机从城市的方向飞来，降落在山岭背后树林中隆郝公司的下属矿曼陀拉矿的停机坪上。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

雅山晚阶段黄玉锂云母花岗岩的长石矿物是富磷长石，磷以PAlSi〓替换方式进入长石结构中，并且在长石中的分布很不均一，一般是晚结晶的长石比早结晶的长石的磷含量高，同期结晶的钠长石比钾长石的磷含量高；锆石矿物为高度富铪、铀、磷和铝的锆石，磷主要以(Y， HREE， Fe)〓P〓〓〓Si〓〓、Al〓P〓Si〓〓、P〓Al〓Si〓〓Zr〓〓等替换方式进入锆石晶格中，富磷锆石是岩浆高度演化的结果，是高磷花岗岩的特征矿物之一；雅山含有丰富的磷锂铝石，是高磷花岗岩的主要磷酸盐矿物；铌—钽矿物主要有铌锰矿—钽锰矿、锡锰钽矿—钛锰钽矿、细晶石等。
