    Antimony Mining - Encyclopedia of Arkansas

    Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). Mined ore deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins. Antimony mining took place intermittently in Arkansas after the metal’s discovery in 1873.

    Stampede Creek and the Legacy of Mining: Antimony in ...

    When the exposure of antimony orebodies to oxidizing surface environments (air) is accelerated through mining, the weathering of the sulfide-rich ores results in the release of oxidized metals (e.g. iron, copper, lead), metalloids (e.g. arsenic, antimony), and sulfuric acid to the local surface and near-surface waters.

    Antimony Ore MSquare Mining

    Antimony is a lustrous tin-white metal. Although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid. The antimony ore found in our mine is Stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process.

    Antimony - North of 60 Mining News

    "Antimony is often a high-level indicator of deeper gold deposits," said Barker. Later investigations by Bear Creek Mining included samples topping 1 oz/t gold, as well as antimony-rich samples with gold, silver and arsenic. Hed and Strand, a mine in the Lost River area about 85 miles northwest of Nome, also produced antimony during World War I.
