查询词典 active volcano

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。
