To study the sweetening process of diasporic bauxite,Al3 obtained from the direct carbonization of unrefined sintering solution was used as the additive and its performance was compared with that of the conventionally used gibbsite .

分别以烧结法粗液直接进行深度碳分所得到粗氢氧化铝和工业上常用的三水铝石矿作为添加剂，进行了一水硬铝石矿增溶溶出过程的对比研究，主要考察了增溶温度、添加剂添加量和增溶时间等因素对溶出效果的影响，同时对增溶溶出矿浆与常规拜耳法溶出矿浆的沉降性能进行了对比研究。

Their formation is not only directly related to granitic intrusions but also controlled by factors such as regional strata and geological structure.

对湘南锡矿形成的地质背景和找矿方向进行研究，不仅能解决锡矿找矿中存在的许多重要的科学问题，为进一步寻找锡矿资源指出方向，而且对认识湘南地区地质构造演化史、探讨花岗岩类及其锡矿床的形成环境也具有特别重要的意义。

Data of major andminor elements in magnetite, cassiterite, galena and sphalerite from oredeposits within this ore belt suggest that these ore deposits are of skarn,hydrothermal, porphyry and greisen types related to Yanshanian magmaticactivity and that iron in ores came from regional Permian marine interme-diate-basic volcanic rocks whereas partial lead and zinc from Permian geo-synclinic sediments.

矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明，这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床；其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩，部分铅锌来源于区域二叠纪地槽沉积物。

The Maoping tungsten-tin deposit is located in the eastern section of Nanling metallogenic belt, the Chongyi-Dayu-Shangyou tungsten polymetallic ore concentration area and at the front part of the Tianmenshan rock mass extension with a north trend. Greisen and the quartz vein are the main tungsten-tin mineralization types in the mine area.

茅坪钨锡矿床位于南岭成矿带东段，位于崇－余－犹钨多金属矿矿集区西华山－杨眉寺区段中北部的天门山－红桃岭矿田，为天门山岩体向北倾伏延伸的前锋部位；矿区钨锡矿化类型主要有云英岩型和石英脉型两种。

The value of mineral resources consists of absolute mineral rent and the first differential mineral rent on the basis of effect value theory, default value theory and Marx s ground rent theory.

矿产资源的价值理论以效用价值理论和稀缺价值理论为基础，加上马克思的地租理论，从而可以得出矿产资源的价值由绝对矿租和第一级差矿租两部分组成。

In order to accelerate the leaching rate of zinc in alkaline solutions, QM-1SP type planetary ball mill was used to enhance the leaching of hemimorphite from Lanping, Yunan Province in NH3-NH4Cl solutions.

摘 要：为了提高异极矿在碱性溶液中的浸出效率，采用QM-1SP行星球磨机对云南南坪异极矿进行机械活化强化浸出研究。

An oxidized zinc ore from Inner Mongolia was found to be very difficult to treat due to its features of high oxidation rate,heavy weathering and the intimate association of hemimorphite and limonite.

内蒙某氧化锌矿石氧化率高，风化严重，异极矿和褐铁矿共生关系紧密且复杂，是一个难选的氧化锌矿。

乙级：水文地质调查；工程地质调查；环境地质调查；岩矿鉴定与岩矿测试。

Main useful minerals in these two ore belts include anatase, rutile and ilmenite.

这2个矿带的主要有用矿物为锐钛矿、金红石及钛铁矿。

This paper introduces the ore drawing process with the natural caving method and the characteristics of each stage, expounds the flow of the ore drawing management with the natural caving method , and probes into some measures that should be adopted in the special condition to reduce the interfusion of waste rock.

介绍了自然崩落法的放矿过程及各阶段的特点，阐述了自然崩落法放矿管理流程，探讨了在特殊条件下应采取的特殊措施，以减少废石的混入。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
