The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2 The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves.
