At this plant near Bingham Canyon Utah copper concentrate is turned into metal in a process called smelting. Smelting heats up the concentrate at very high temperatures and removes most impurity elements. Subsequently iron and sulfur are removed in the conversion process. The molten copper is then poured into molds.

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. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This
