Antimony is found in over 100 minerals, most of which are quite scarce. By far the commonest is stibnite, the primary sulphide, which has the formula Sb₂S₃.

Bristol City Museum and Art Gallery has a fascinating mineral section, with a sample of native antimony, and three very different, stunning examples of stibnte, showing its needle-like crystals. A visit is highly recommended.

A summary of some of the main minerals in which antimony can be found is given below.
