Some 2/3 of copper production at Aurubis is based on copper concentrates (primary raw materials) supplied by the mines. Concentrates are composed of copper, iron and sulfur in equal parts. 1/3 of the copper production is based on recycling materials, such as copper and copper alloy scrap, copper-bearing residues from foundries and semi-finished product fabricators, shredder materials as well galvanic slimes, slags, ashes and filter dusts.
