首先，銅的再生性能使其能夠被不斷循環利用。理論上來說，銅可以被百分之百地回收利用。并且，無論經過多少次回收，銅在經過精煉之后都能保持其延展性、導電和導熱性及抗腐蝕等基本屬性，具有極佳的再生性能。這意味著銅雖非“采之不竭”，卻可以在被消耗的同時不斷地進行補充和累積。 First of all, the regeneration performance of copper enables it to be continuously recycled. Theoretically, copper can be recycled by one hundred percent. Moreover, no matter how many recycling, the copper can maintain its basic properties such as ductility, conductivity, heat conduction and corrosion resistance after refining. It has excellent regeneration performance. This means that the "mining of copper is not inexhaustible, but can be consumed at the same time constantly supplement and accumulation. 據我國國土資源部預測，2050年前后，我國人均銅累積量將達到峰值，而國內循環利用銅即可完全滿足消費需求，銅在我國將不再是一種長期短缺的資源。不僅如此，從生態保護的角度來看，發展銅的再生利用，可以有效避免開采過程中產生的能耗和固體廢棄物的排放，在環保和可持續發展層面上也具有重要的意義。 According to the Ministry of land and resources, according to the Ministry of land and resources of China, the per capita copper accumulation in China will reach the peak before and after 2050, and the domestic recycling of copper can fully meet the consumption demand. Copper in China will no longer be a long-term shortage of resources. Not only that, from the point of view of ecological protection, the development of the recycling of copper can effectively avoid energy consumption and solid waste emissions in the process of mining. It is also of great significance on the level of environmental protection and sustainable development. 其次，銅的儲采比高，能夠保證較長的可開采及使用年限。長久以來，“中國富鋁缺銅”的說法一直塵囂甚上。在很多人的概念中，相比其他資源而言，我國銅的儲存量并不高，至少從儲量上來說，銅絕對不占優勢。但這個概念背后其實存在一定的誤區。 Secondly, the copper reserve production ratio, to ensure long service life and can be mined. For a long time, "China aluminum rich copper" has been quite noisy. In many people's concept, compared with other resources, China's copper storage is not high, at least from reserves, copper absolutely has no advantage. But there are some misunderstandings behind this concept. 這就不得不提到“儲采比”的概念。儲采比又稱回采率或回采比，指年末剩余儲量除以當年產量得出剩余儲量，按當前生產水平尚可開采的年數。根據我國國務院發展研究中心有關數據統計，2014年，我國銅礦產資源探明儲量為3000萬噸，儲采比為19左右，有逐年上升的趨勢，而同年鋁的儲采比僅為7，比2003年下降了近20。因此，從儲采比這一點上來看，銅資源相較于鋁而言，也更有保障。 This had to mention the concept of "ratio". The reserve production ratio, also known as the recovery rate or the recovery ratio, refers to the remaining reserves at the end of the year divided by the year's output and the number of remaining reserves that can be mined according to the current production level. According to the data statistics of the development research center of the State Council, in 2014, the proven reserves of copper mineral resources in China are 30 million tons, and the storage and production ratio is about 19, and there is a trend of increasing year by year, while the storage and production ratio of aluminum in the same year is only 7, which is nearly 20 lower than that in 2003. Therefore, from this point of view the reserve production ratio, compared with aluminum copper resources, and more security.
