The first mineral discovery by the Russians in Alaska ( a cinnabar-stibnite deposit ) occurred in the Aniak district in 1838.
32.
The hammer-and-chisel mining method used at Ichinokawa is one reason that so many high-quality stibnite crystals were extracted.
33.
It commonly occurs with galena, tetrahedrite, sphalerite, chalcopyrite, pyrite, stibnite, zinkenite, siderite, quartz, rhodochrosite, dolomite and barite.
34.
Associated minerals include stibnite, realgar, orpiment, cinnabar, vrbaite, greigite, marcasite, pyrite, tetrahedrite, antimonian sphalerite, arsenic and barite.
35.
These hot fluids contained gold, silver, antimony and sulfur which, as the waters cooled, left behind minerals like pyrite, stibnite and scheelite.
36.
The 17th century alchemist Eirenaeus Philalethes, also known as George Starkey, describes stibnite in his alchemical commentary " An Exposition upon Sir George Ripley's Epistle ".
37.
It occurs associated with pyrite, sphalerite, wurtzite, galena, stibnite, orpiment, realgar, enargite, tetrahedrite, zinkenite, jordanite, bournonite, sterryite, boulangerite, jamesonite and sartorite at Madoc.
38.
Kermesite is the result of partial oxidation between stibnite ( Sb 2 S 3 ) and other antimony oxides such as valentinite ( Sb 2 O 3 ) or stibiconite ( Sb 3 O 6 ( OH ) ).
39.
It includes exquisite examples of amethyst, apatite, stibnite, copper, tungsten, molybdenum, vanadium, cobalt, nickel, mercury compounds, aluminum compounds, malachite, lapis-lazuli, tourmaline, garnet, labradorite, fluorite, beryl, and turquoise, among others.
40.
Common naturally occurring sulfur compounds include the sulfide minerals, such as pyrite ( iron sulfide ), cinnabar ( mercury sulfide ), galena ( lead sulfide ), sphalerite ( zinc sulfide ) and stibnite ( antimony sulfide ); and the sulfates, such as gypsum ( calcium sulfate ), alunite ( potassium aluminium sulfate ), and barite ( barium sulfate ).
