Antimony Mining
Antimony mining took place intermittently in Arkansas after the metal's discovery in 1873. Smelting attempts were made first in 1887 but were unsuccessful. The first commercial production was recorded in 1889. Mining activity peaked during World War I when metal prices were high, and sporadic efforts to continue mining ended in 1924 …
