在人类的发展史中,金属资源的开采和冶炼始终影响着时代的进步。随着人类生产力的大幅度提高和人口爆炸,天然资源的使用激增,使地球丰富的金属材料日趋消耗殆尽。因此,对现有的金属资源应予以保护,防止金属腐蚀,同时也应对已经腐蚀的金属进行回收再利用。铜金属作为人类早期发现的金属之一,同时也作为当今人类使用广泛的金属之一,其在日常生活和工业领域的重要性不言而喻。若以现今铜矿的开采速度计算,世界已知的铜金属资源将会在25~60
In the history of human development, the exploitation and smelting of metal resources have always influenced the progress of the times. With the drastic increase in human productivity and the population explosion, the use of natural resources has surged, depleting the earth’s rich metal materials. Therefore, the existing metal resources should be protected to prevent metal corrosion, but also should have been corroded metal recycling. As one of the early metals found in human beings, copper metal is also one of the most widely used metals in the world today, and its importance in daily life and industry is self-evident. If the current copper mining rate calculation, the world’s known copper metal resources will be in the 25 ~ 60
