Recoverable urban mine was defined as the amounts of material stock which can be going to be recycled. End-of-life recycling rates of metallic materials for each year in the past two decades were evaluated. The time-series EoL-RR showed a deviation of more than twenty percent. High EoL-RRs were shown during a period when prices of the material are high, which were expected to be caused by hibernating behavior of material stock. Four category of Urban mine were classified in terms of recoverability; such as materials to be recovered, dissipated materials, materials embedded in EoL products not to be recovered and materials not to be liberated from recovered EoL products. The evidence of the fourth category was found as precious metals in electric arc furnace steel. As summarizing knowledge of recyclability of urban mine, the tree of conditions which required for conducting processes in the chain of recycling from EoL products.

可回收的城市矿山被定义为可回收的物料存量。对过去二十年来每年金属材料的报废回收率进行了评估。时间序列EoL-RR偏差大于20%。较高的eol - rr出现在材料价格较高的时期，预计这是由于材料库存的冬眠行为造成的。按可恢复性将城市矿山分为四类；如需要回收的材料、耗散的材料、嵌入不需要回收的EoL产品中的材料以及不需要从回收的EoL产品中解放出来的材料。第四类的证据是在电弧炉钢中发现的贵金属。通过对城市矿山可回收性知识的总结，得出了EoL产品回收链中各工序所需条件树。
