金属矿石

Huangshaping Pb-Zn deposit originated from high-middle temperature solutions. Structures developed in area consist of NNE-striking folds, N-S and nearly E-W faults system. There are Upper Devonian and Lower Carboniferous outcropped, and the Shidongzi Formation limestone of the later is the main host rock. Ore body has various shapes with a great number of minerals and complex chemical compositions.

黄沙坪铅锌矿床属高中温热液成因的金属矿床，矿区内构造主要包括北北东向为主的褶皱和南北向、近东西向为主的断裂构造系统；出露地层主要有上泥盆统和下石炭统，其中下石炭统石磴子组灰岩为主要赋矿围岩；区内矿体形态多样，矿石矿物种类繁多，化学成分复杂。

Gold mining was developed to obtain ore from which the pure metal could be extracted.

黄金采矿被发展获得矿石从哪一纯粹的金属可能被吸取。

That is a far higher gold content than Japan's Hishikari Mine, one of the world's top gold mines, owned by Sumitomo Metal Mining Co Ltd (5713.T ), which contains 20-40 grammes of the precious metal per tonne of ore.

这个黄金含量远远高于日本菱刈矿山，而菱刈矿山是世界上顶级矿山之一，由住友金属矿业有限公司所有，它在一吨矿石中含有20-40克的贵金属。

The permeability of ore mass has a great influence on the leaching period of heap leaching and the leaching efficiency,hence the uranium ore s with high content of clay is difficult to acidic heap leaching.

矿堆的低渗透性能是局限矿石浸出周期及金属浸出率的最主要因素之一，因此，长期以来，高含泥量的铀矿石一直是酸法堆浸提铀技术的应用禁区。

Gold occurs mainly in pyrite-sericite-quartz rocks and pyrite±polymetallic-sulphides+quartz±carbonate veins and stockworks, forming veinlet-disseminated ores.

金主要产于黄铁绢英岩和黄铁矿±多金属硫化物+石英±碳酸盐脉-细网脉中，构成细脉-浸染状矿石。

The floatation process of a multi-metal sulfide ore from Anwang Silver-lead Mine in Shaaxi,China,is investigated.

研究陕西省山阳安旺铅银矿多金属硫化矿石浮选工艺。

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。
