矿石

It can carry on the measurement of various kinds of oceanography key elements and geophysics parameters, photography, sea the floor of sea, take a geology sample salvage the ore in the depth in the ocean and maintain and repair underwater regular industrial facility through the equipment, investigation.

借助这些装备可以进行各种海洋学要素和地球物理学参量的测量、海底的考察和摄影、海底铺设电缆、地质取样及打捞蕴藏在大洋深处的矿石、水下固定工业设施的使用维护和修理等。

Supporting by this software system, the process of simulating ore exploration is as follows, fixing up sections of exploration and project design, arranging section project and simulating constructing result, layouting samples with mineralization and simulating sample grade, blocking-out ore bodies and calculating reserves, and simulating valuating exploration results based on costs of project and reserve unit.

在该软件系统的支持下，对矿床进行模拟勘查的步骤如下：布置勘探剖面及形成工程设计剖面；布置剖面上的工程及模拟施工结果；布置见矿孔段的样品及模拟矿石品位；圈定矿体及储量计算；根据工程总成本及储量单位成本等指标，对勘查结果的评估做出模拟。

According to the heavy-liquid separation test, the embedded granularity survey of tungsten minerals and shaking-table test of ore sample grading, the -0.7 mm granularity is determined to be selected for the gravity concentration test. The ores will be smashed below -0.7 mm . The useful minerals should not be excessively smashed. The reasonable technology procedure of ore grinding can guarantee the indexes of gravity concentration in a long length.

依据重液分离试验结果、钨矿物嵌布粒度结果及矿样分级摇床试验结果，确定重选试验的入选粒度为-0.7mm ，欲将矿石碎至-0.7mm 以下，又使有用矿物尽可能减少过粉碎，选择合理的磨矿工艺流程是确保重选指标的关键。

It is the first specially large marine facies stratificated salt mine bed.

四川威西岩盐体储量极为丰富，矿石品位高，埋藏深度适中，矿床开采技术条件和自然经济地理条件良好，是我国第一个特大型海相层状盐矿床。

And the thin degree of mineral is very thin. If want to achieve the rich purpose to collect the iron through rub the tailing again to separate the silicon and irons from the ore, it is very difficulty and the cost is too expensive.

由于浮选后的精矿品位不高，尾矿产生量大，其铁品位在43%左右，且原矿磨矿细度已经很细，如果想通过尾矿再磨，分离矿石中的硅和铁，达到富集铁的目的，难度很大，且成本不合算。

Consequently,it is possible to discriminate the tectonic setting of ore-forming and rock-forming by studying major elements of sandstones in Dayao sandstone copper mine.

大姚砂岩铜矿成矿受氧化-还原环境控制，分析大姚六苴矿床岩石和矿石样品的F e2+/F e3+值与铜元素含量之间的关系，探讨砂岩铜矿的氧化-还原环境特征，从而建立大姚砂岩铜矿的地球化学相。

Some so-called natural vitamin may be made of dead beef liver, coal tar or petro-chemicals? And some so-called natural minerals are made of mined ore powder, calcium from ground up oyster shells.

一些所谓天然的维他命可能是从死牛肝、煤焦或石油化合物炼制而成的，而一些所谓全天然的矿物质只不过是矿石的粉末，钙则是蚝壳的粉末，人体绝不容易去吸收这些所谓的「天然物质」！

In the process of converter smelting, a fair quantity of iron oxide ball with high grade, low moiwture content and low in purity is added to converter instead of ore as the adjusting agent of temperature and slag.

在转炉冶炼过程中向炉内试验加入一定量的含铁品位高、水分少、杂质低的氧化铁球来代替矿石，作为转炉调温调渣剂，结果表明，加入氧化铁球后，转炉反应平稳，调渣迅速，不会产生剧烈反应造成喷溅，并有利于提高金属收得率。

Metallurgy Engineering studies the production of metal and metallic compounds from ore or other resources, and the production of metallic materials with good processibility and performance.

冶金工程是研究从矿石等资源中提取金属及其化合物、并制成具有良好加工和使用性能材料的工程技术领域。

On-line measuring of metallic ore powder particle is the main puzzle that confronts the researcher who is engaged in particle size research of the powder particle.

金属矿石粉末颗粒粒度的在线检测问题，一直是从事粉末颗粒粒度检测技术研究人员所要面对的难题之一。
