Mineralogy of Antimony Ores and Antimony Production

The English word antimony is derived from the Greek words anti [opposed] and monos [solitude] which means a metal that rarely occurs alone [] Native antimony has a strong affinity for sulfur and other metals such as copper lead and gold [] [] As a result the development of extraction methods was very slow until the Japanese war in 1905
