Silver

Aurubis doesn't only produce copper and copper products but also precious metals like silver as granules and bars.

Production process for silver granules and bars

By casting the silver melt through a stainless steel sieve, the casting stream is separated and cooled abruptly in a turbulent water quench. Small silver balls are formed, called fine silver granules. These are dried and packaged for shipment in the containers requested by the customer. Fine silver can also be cast into bars.

Silver is only sold to commercial users/consumers. VAT is invoiced in the reverse charge procedure in accordance with Section 13b of the German Value Added Tax Act (UStG).

Sustainability

Transparency through product data

Metals are essential to the modern world, and transparency is key to reducing their environmental impact. For five years, Aurubis has published independently verified Environmental Footprint Declarations (EFDs), based on Life Cycle Assessment methodology and verified by TÜV NORD. In 2026, we now cover 14 product groups, pioneering transparency in our industry. Where comparable benchmarks exist, our products perform better. Where they don't, we are setting new standards for transparency. Because reliable data enables better decisions, measurable progress and more sustainable value chains. Our contribution to a net-zero future.
