Silver Granules & Silver Bars

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).
