Why is this extraction process used? Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle. That means that you have to use an alternative reducing agent. In the case of titanium ...

Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements. Ores are rocks containing enough metal to make it economical to extract. We can extract the iron by reacting the iron oxide with a more reactive element.
