Antimony is not common. It is found about as often as thallium. It is quite easy to get, though and is in many minerals. Antimony is sometimes found as an element, but normally it is found as stibnite, an antimony sulfide mineral. Stibnite is the main ore of antimony. China is the biggest maker of antimony; it makes 84% of all antimony. Other countries that make antimony are South Africa, Bolivia, and Kyrgyzstan. Antimony is not used in the human body.
