矿石

In view of the problem of deep deposits caving minning, through the recalling of deep deposit caving mining new technologies, sublevel caving with throughout-frontal ore drawing is put forward, which can recall all of the rocks of the ore, and the ore has the best recovery parameters, the high extraction strength, more favorable conditions of work safety.

针对深厚矿床崩落开采法的问题，通过回顾深部矿床崩落开采法的新技术，提出改进的端部放矿分段崩落采矿法，在矿井能够从跨落的岩石下回收所有的矿石，具有最好的矿石回收参数，高开采强度，较有利的安全的工作条件。

Focus on the situation that a certain number of low grade nonindustrial ore existed in Nanfen Iron Mine ,the feasibility and necessity of recovering and utilizing the low grade nonindustrial ore is expounded mainly from the viewpoint of the rational utilization o

针对南芬铁矿采场存在一定数量低品位非工业矿石的实际情况，主要从资源合理利用的角度阐述了回收利用低品位非工业矿石的可行性和必要性。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter

矿石中的天然固有杂质对矿石质量的影响最为严重。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter

正是矿石中与身俱来的杂质，严重影响了矿石的品质

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter

影响矿石质量的因素不是别的，正是矿石中天然固有的杂质。

Oe the basis that stockpiling low grade ore necessitates the expense of rehandling, process the low grade ore directly from the pit, thus freeing up potential storage volume for waste rock.

在储蓄低等级矿石成为直接从矿坑中直接处理，加工这些矿石的必要一节后，要尽可能的寻找跟占用空间来处理废石。有些意思是猜的。

The results of static analysis on these reserves show that the residual geological reserves of both Lujing and Huangfengling deposit belong to sub-profitable type, but the ones of Yangjiaonao deposit is profitable with 26.56% tax-before profit. 1 tU profitable type of ore from Yangjiaonao deposit can use 2.40~3.79 tU subprofitable type of ores from Lujing and Huangfengling deposit.

静态分析结果表明，鹿井、黄蜂岭矿床的剩余地质资源属于次经济类型，而羊角脑矿床的地质资源属于经济类型，其税前利润率达26.56%，具有较好的赢利能力。1 tU的羊角脑矿床的经济型矿石可盘活2.40~3.79tU不等的鹿井和黄蜂岭矿床的次经济型矿石。

The leaching test shows that Pb/Zn ore are susceptibly to be oxidized or dissolved and readily release Cd and other harmful element.

两个不同矿石镉的淋失量有所差别，矿石中菱锌矿质量分数是影响镉淋失的主要因素。

The process of burning .live coals; tossd a live cigarette out the window; got a shock from a live wire; live ore is unmined ore; a live bomb; a live ball is one in play.

燃烧着的煤；把一根燃烧的香烟扔出窗外；被有电的电线打了一下；天然矿石就是没有开采的矿石；装有炸药的炸弹；活球就是正在打的球。

To charge with dynamite .The process of burning .live coals; tossd a live cigarette out the window; got a shock from a live wire; live ore is unmined ore; a live bomb; a live ball is one in play.

燃烧着的煤；把一根燃烧的香烟扔出窗外；被有电的电线打了一下；天然矿石就是没有开采的矿石；装有炸药的炸弹；活球就是正在打的球。

Do you know, i need you to come back

你知道吗，我需要你回来
