Metal Production from Concentrates - Aurubis

Copper ores contain about 0.5-4 % copper and are already processed into a concentrate in the mine. The concentrate is a finely milled, dark gray material containing about 30 % copper (Cu), 30 % iron (Fe) and 30 % sulfur (S). The concentrate also often contains small amounts of precious metals and a range of other elements, which we process in the smelters.
