Mining operations and mints generate large volumes of high-metal-content waste, such as slag, tailings, and rejected or damaged coins. In mints, scrap silver and gold from stamping and refining processes are collected and remelted. Mining waste, although more diluted, contains residual precious metals that can be recovered with advanced technologies. Both sources are essential for refining operations, contributing a steady stream of recyclable metal. Effective recycling reduces environmental damage from mining and increases the sustainability of metal supply chains.
