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 metals discovery in 1873.Online Chat
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite antimony sulfide and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.Online Chat

Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold. The only significant ore mineral of antimony, stibnite Sb 2 S 3 , is widespread as an accessory mineral in gold-bearing quartz veins, particularly in veins that intersect the Silurian Early Devonian Murrindindi Supergroup sedimentary rocks of the Melbourne Zone.Online Chat
Antimony is a silvery-white metal that is found in the earths crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. 1 Antimony trioxide is a white powder that is very slightly soluble in water. 1 Antimony metal is a very brittle, moderately hard metal. 1Online Chat
