Antimony is considered to be one of the most toxic of the heavy metals, and therefore has lower limits than other metals except cadmium (Cd) and mercury (Hg). Antimony uses Antimony was used in gold extraction and purification for thousands of years, and the antimony sulfide, stibnite (Sb 2 S 3 ) was used in ancient times for cosmetic purposes.
