Antimony Metallurgy
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.
