人们对于金属并不陌生,它是当今世界应用最广泛的固体材料.随着科学技术的发展,人们对于新型金属材料的研究给予十分重视,并取得很大的成就.但是,人们对金属回收利用的科研工作重视不够,认为金属回收无科研可言。这主要是人们对于金属回收工作不甚了解,以为回收仅仅是将废金属加以分类、挑选、加工成合格的炉料而已。其实不然,现代工业耗用大量的、种类繁多的各种轻、重、贵、稀有金属,由于各种金属、合金的化学成分不同,回收各行各业的废金属不但范围广,而且技术性很强,回收
People are no stranger to metal, it is the most widely used solid material in the world today.With the development of science and technology, people attach great importance to the research of new metal materials, and made great achievements.However, people recycle metal The importance of scientific research is not enough, that there is no scientific research at all. This is mainly because people do not fully understand the metal recycling work and think that recycling is just a matter of sorting scrap metal, selecting it, and processing it into a qualified charge. In actual fact, the modern industry consumes a large variety of light, heavy, expensive and rare metals. Due to the different chemical compositions of various metals and alloys, the recovery of scrap metal from all walks of life is not only extensive but also highly technical , Recycling
