Abstract

The recovery of copper ( Cu ) from secondary sources has received much attention because of its scarcity of natural resources. In this work, we estimated the input, in - use stock and discard of copper and copper alloy during 1950 - 2015 in global scale, and forecast them until 2050. In addition, we estimated the potential of scrap recovery for copper / copper alloys. It was estimated that the total amount of in - use stock of copper and copper alloy were 177 , 000 kt and 44 , 200 kt in 2015, respectively. The in - use stock, discard and input of copper in 2050 will reach 381 , 000 - 588 , 000 kt, 15 , 400 - 22 , 200 kt and 18 , 990 - 33 , 000 kt, respectively, whereas those for copper alloy will reach 77, 500 - 134 , 000 kt, 3 , 020 - 4 , 680 kt and 3 , 760 - 7 , 200 kt, respectively. The copper content in recov - erable scraps of copper and copper alloy will reach 15 , 100 - 27 , 300 kt, and this accounts for 55 . 1 - 79 . 0 % of copper content in annual input of copper and copper alloy in 2050. The range in forecast was caused by the difference in the saturation amount

全球范围内铜及铜合金的动态物料流分析-在用库存和投入预测及废料回收潜力估算
从二次源中回收铜由于其天然资源的稀缺性而备受关注。在这项工作中,我们估计了1950 - 2015年全球范围内铜和铜合金的投入、在用库存和丢弃量,并预测了它们到2050年的变化。此外,我们估计了铜/铜合金废料回收的潜力。据估计,2015年中国铜及铜合金在用库存总量分别为17.7万吨和44.20万吨。2050年,铜的使用存量、丢弃量和投入量将分别达到38.1万~ 58.8万kt、1.54万~ 2.22万kt和1.990万~ 3.33万kt,而铜合金的使用存量、丢弃量和投入量将分别达到7.75万~ 13.4万kt、3.020 ~ 4.68万kt和3.760 ~ 7.20万kt。铜及铜合金可回收废料中铜的含量可达15、100 ~ 27、300 kt,占总铜的55%。1 - 79。2050年铜及铜合金年投入中铜含量达到0%。预报偏差是由于饱和量的差异造成的
