Oct 03, 2013  Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Other more reactive metals can be used to reduce the ore.

The Metal Reactivity Series – Compound Interest

Mar 10, 2015  This extraction is possible because iron is below carbon in the reactivity series, and works similarly well for other metals below carbon. However, with some metals, metal-carbon carbide compounds are formed, which can cause the metal to be brittle. For this reason, other extraction methods are sometimes necessary.
