矿石

He eventually hopes to use rock - cutting ROVs that will drive across the sea floor, grinding ore as they go and sending it to the surface via a tube at a rate of 400 tonnes per hour.

事实上，他希望可以用岩石切割的深海探测工具，这种工具将可以再深海大陆上行进，在经过矿石时把它打磨下来并通过一条每小时能传送400吨的管道传送到地面。

Owner Chen Hou-hua believes that the current economic crisis is already feeling the impact of a number of factories in southern Jiangsu closed or reduced production, and some construction sites slowed down the progress of the works, especially the iron and steel enterprises along the river, sea Jin Jiang ore decline in demand, the impact of the transport business.

船主陈厚华认为，目前已感到经济危机的影响，苏南的一些厂关门或减产了，一些建筑工地的工程进度放慢了，特别是沿江的钢铁企业，对海进江矿石的需求下降，影响了运输生意。

Because of the quality of ore, blast furnace characteristics of the relationship between medium-sized steel enterprises mainly long association mining, we simulated the second quarter, compared with the spot price of Australian mine co-lowest out of 10%-20%, but assuming that Australian iron ore price agreement long in the third quarter rise about 23%, sea freight and ore spot prices remain unchanged in the next six months, then we simulated the third quarter than the spot price of Australian mine co-7.8% higher price.

因矿石品质、高炉特点等关系，大中型钢企主要采用长协矿，我们模拟的二季度澳矿长协价较现货价低出10%-20%，但如果假设澳矿三季度长协价再涨23%，现货海运费和矿价在未来六个月均保持不变，那么我们模拟的三季度澳矿长协价较现货价高出7.8%。

Additional features include a screw-down case and crown, a scratch-resistant Hardlex crystal, and a one-way rotating bezel that keeps track of elapsed time.

其它特点包括一个螺旋式的情况和冠，一防刮矿石高强化玻璃，以及单向旋转表圈的保留了运行时间的轨道。

Some coarse gold tin chute chute and sand followed are still used. The mid-19th century, experienced a mechanical transmission belt chute chute and round, becoming one of the major fine-grained non-ferrous metals ore sorting equipment.

有些粗粒砂金溜槽和砂锡溜槽沿袭至今仍有使用。19世纪中叶出现了机械传动的带式溜槽和圆形溜槽，成为当时细粒有色金属矿石的主要选别设备。

The first sample of ore from the trial boring is very promising, but we should remember that one swallow does not make a summer.

从试钻的第一决矿石样品来看那是很有开采价值的，不过我们应该记住不可光凭偶然现象就下断语。

A forty tonne bulk sample of Yerilla ore has been shipped to Changsha for this test work.

40吨散装样本Yerilla矿石已运到长沙的这一试验工作。

The first sample of ore from the trial boring is very promising, but we should remember that one swallow doesn't make a summer.

To pay a casual visit.The first sample of ore from the trial boring is very promising, but we should remember that one swallow doesn't make a summer.

从试钻的第一决矿石样品来看那是很有开采价值的，不过我们应该记住不可光凭偶然现象就下断语。

Precious metals tend to occur as scattered particles randomly distributed, so a large sample of ore is required.

贵金属因分散颗粒无规则地分布，分析时需要取用大量矿石样品。
