Raw materials

Copper concentrates

Aurubis Bulgaria’s main source of copper raw materials is the copper concentrates produced by the copper mining industry. We smelt more than 1.2 million tons of copper concentrates originating from North and South America, the Black Sea region and Bulgaria. The imported copper concentrates are delivered by bulk vessels to the Port of Bourgas and railed to the Aurubis plant in Pirdop.

Aurubis maintains weighing and sampling control operations at the Port of Bourgas for establishing weight and sampling of the copper concentrates. Quality is controlled by our certified laboratory.

Recycling

Aurubis Bulgaria is the largest copper recycler in Southeastern Europe. We recycle No 1 copper scrap (Berry), No 2 copper scrap (Birch/Cliff), bronzes and granulated copper. Waste copper is converted into pure LME Grade A copper cathodes in the three stages of copper refining.

Aurubis continuously invests in recycling facilities to provide the most modern standard of recycling in a green and sustainable way.
