Open-pit copper mining, smelting, and production
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 heavy copper plates that have been shaped are called anodes. In the final extraction step—refining—any remaining minor
