It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

影响矿石质量的关键是其所含杂质的多少，其成色高低受一系列地质变迁，如地壳运动，火山爆发，沉积运动，冰川运动及风化侵蚀等作用影响，经过高温成岩，火山熔岩，含水岩，水成岩等过程形成，部分以共生态存在。自然界纯矿石稀少，因此我们需要使用分离技术和设备，即筛矿装置和器械，但目前的设备已不能满足冶矿业的需求，科学家们正试图以激光筛选使选矿技术达到一个新的水平。

Despite political tensions in the country, its huge deposits of gold and other metals are proving too big a temptation for foreign miners, David Eimer reports from Beijing

尽管国内政治局势紧张，但是中国疆土上充满黄金及其他金属的大型矿床对国外矿业公司来说是一个无法抵制的巨大诱惑，大卫·埃姆尔从北京发回报道。

If Australia's BHP Billiton succeeds in ensnaring Rio Tinto, steelmakers - led by the Chinese - will find themselves trying to bargain down a miner which produces more than one-third of the world's iron ore.

如果澳大利亚的必和必拓成功地将力拓收入囊中，那么以中国厂商为首的钢铁制造商将发现，自己的谈判对手是一家占全球铁矿石产量逾三分之一的矿业巨头。

As the Anglo-Australian miner and the Chinese metals group endure a third month of trying to seal their geopolitically sensitive proposal in which Chinalco will make a $19.5bn capital investment in Rio it appears that no one has an answer to these questions.

双方试图敲定这宗地缘政治敏感提议的持久战已进入第三个月，但似乎没有人能回答这些问题。根据提议，中国金属集团中铝将向英澳矿业集团力拓注资195亿美元。
