Faced with ever‐severe gold mineral depletion, obtaining a sustainable gold resource by utilization of accumulating waste electrical and electronic equipment (WEEE) is of vital importance. Inspired by fischesserite, the first naturally occurring selenide of gold, a novel selenium‐containing polyurethane (Se‐polyurethane) is prepared. This material is able to extract aqueous gold in its elemental form with a selectivity 437 times over Cu²⁺ and 443 times over Ni²⁺ and a capacity of 802 mg gold g^‐1. The extracted gold can be collected through a noncalcination post‐treatment procedure and the Se‐polyurethane can be recycled via a convenient regeneration procedure. Derived from this material, a high‐throughput circulating aqueous gold mining system and a crosslinked Se‐sponge are illustrated to mimic dynamic and static extraction processes, respectively for possible industrialization. These selenium‐containing materials have the potential to be a useful tool in gold extraction to help prevent future resource depletion.

Fischesserite启发的可回收硒聚氨酯，用于选择性金提取

面对日益严重的金矿耗竭问题，利用堆积的电气和电子废旧设备（WEEE）获得可持续的金矿资源至关重要。受到菲希塞特（天然的第一种金硒）的启发，制备了一种新型的含硒聚氨酯（Se-聚氨酯）。这种材料能够提取水性金以其元素形式与选择性超过铜437倍²⁺在Ni和443倍²⁺和802毫克金g的容量^-1。提取的金可以通过非煅烧后处理程序收集，而硒聚氨酯可以通过方便的再生程序进行回收。从这种材料中衍生出来的高通量循环含水金矿开采系统和交联的Se-ponge分别用于模拟动态萃取和静态萃取过程，以实现可能的工业化。这些含硒材料有可能成为提金的有用工具，以帮助防止将来的资源枯竭。
