  • How does the process of smelting purify metal ores?

    Copper smelting is a 3 stage process. First the iron is removed by heating the ore with silica. The iron is oxidised and reacts with the silica to form a slag, which can be drawn off separately. Next the remaining copper sulfide is heated to a higher temperature and air blown through to burn off the sulfur which forms sulfur dioxide.
