Antimony trisulfide

IDENTIFICATION AND USE Antimony trisulfide is a solid grey or red-orange It is used in pyrotechnics as well as in the manufacture of ruby glass matches explosives and as a pigment in paints HUMAN STUDIES Workmen in a plant where antimony trisulfide was used were studied focusing on cardiovascular status Antimony sulfide Stibnite chemical inhibitors ABSTRACT Fouling of different components of geothermal power produc-tion is one of the limiting factors in efficient use of the geothermal resources Most common scales are silica calcium carbonate and calcium sulfate while less common are iron iron silicate Ba/Sr sulfate and calcium fluoride

Antimony Properties and

Antimony is a chemical element with symbol Sb (from Latin stibium) and atomic number 51 A lustrous grey metalloid it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3 ) It is a semimetallic chemical element which can exist in two forms the metallic form is bright silvery hard and brittle the non-metallic form is a grey powder silver and antimony from ore reserves within the Stibnite Mining District using modern mining processes infrastructure and logistics to meet worldwide demands Stibnite Gold Project EIS

STIBNITE – Mardani Fine

Stibnite is primarily composed of antimony which has been utilized for over 3 000 years as a component of medicine and as a treatment against "evil spirits " The majority of antimony is ore-grade and is utilized industrially in metal-casting and as a flame-retardant additive in various products such as plastics textiles rubber and adhesives Antimony exists in four oxidation states -3 0 +3 +5 the trivalent (Sb (III)) and pentavalent (Sb (V)) forms are the most common Elemental antimony (Sb) is a silver white metal primarily used to make alloys Other notable antimony species include antimony trioxide (trivalent) and medicinal antimonials – pentavalent antimonials used

Chemical Fact Sheet Antimony

Antimony was recognized in compounds by the ancients and was known as a metal at the beginning of the 17th century and possibly much earlier It is not abundant but is found in over 100 mineral species Most widespread minerals containing Antimony This list of minerals containing Antimony is built from the mindat locality database This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Antimony mineral

Oxidizing Roast Stibnite the
Antimony Mineral

The leading antimony mineral is stibnite In smelting stibnite ore two processes are available precipitation and roasting-reduction The former is suited only for high-grade ores As low-grade ores are more common than high-grade roasting-reduction is of greater importance than precipitation In the roasting process the aim may be to leave the oxidized antimony in the ore or it may be to SUMMARY The Payette National Forest (PNF) is preparing an Environmental Impact Statement (EIS) to evaluate and disclose the potential environmental effects from (1) Approval of the "Stibnite Gold Project Plan of Restoration and Operations" (Plan) submitted by Midas Gold Idaho Inc (Midas Gold) in September 2016

The geochemistry of antimony in hydrothermal solutions

At 30C the stibnite solubility curve was best reproduced by a scheme of five species Sb₂S₄⁻ HSb₂S₄⁻ H₂Sb₂S₅⁻ H₃SbS₂O and Sb(OH)₃ At higher temperatures (≥ 70 C) stibnite solubility at the conditions of the experiments was due to the following four species Sb₂S₄⁻ HSb₂S₄⁻ H₃SbS₂O and Sb(OH)₃ This page was last edited on 5 January 2019 at 20 37 Files are available under licenses specified on their description page All structured data from the file and property namespaces is available under the Creative Commons CC0 License all unstructured text is available under the Creative Commons Attribution-ShareAlike License additional terms may apply

defense tungsten was needed for strengthening steel and antimony for hardening lead manufacturing munitions and making the wooden flight decks of aircraft carriers flame resistant In fact ninety percent of the domestic antimony output and forty percent of the domestic tungsten came from Stibnite Idaho Although not abundant antimony can be found in over 100 species of minerals Most commonly as stibnite Released to the atmosphere from natural sources and as a by-product of smelting lead and other metals it generally drops to contaminate soils and waterways

Geology of the Tungsten Antimony and Gold Deposits

GEOLOGY OF THE TUNGSTEN ANTIMONY AND GOLD DEPOSITS NEAR STIBNITE IDAHO By JOHN R COOPER ABSTRACT The deposits of tungsten antimony silver and gold described in this report occur in an area about a mile wide and 3% miles long near the town of Stibnite Valley County Idaho Ore has been mined from only two deposits in the area Antimony is estimated to compose 0 2 to 0 5 parts per million of the earth's crust and is found in over 100 mineral species It is sometimes found natively but most frequently it is found as the sulfide mineral stibnite

STIBNITE a mineral consisting of antimony sulphide Sb2S3 occurring as bladed or acicular orthorhombic crystals an important ore of antimony It was mentioned by Dioscorides and Pliny under the names stimmi stibi and platyophthalmon (arXarvbcBaXuov) the last name refers to the use which the ancients made of the powdered mineral for darkening the eyebrows to increase the apparent size of Antimony (Sb) - of ancient origin Antimony is sometimes found natively but more frequently it is found in the sulfide stibnite (Sb2S3) which is the predominant ore mineral The largest applications for metallic antimony are as alloying material for lead and tin and for lead antimony plates in lead-acid batteries

Stibnite Antimony Species

  1. It's Elemental

    The Element Antimony It is sometimes found free in nature but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3 ) Nicolas Lmery a French chemist was the first person to scientifically study antimony and its compounds He published his findings in 1707 Antimony makes up about 0 00002% of the earth's crust

  2. Stibnite Mine

    They used antimony in munitions "Gold arsenic antimony and mercury typically occur together and that was a much younger mineralizing event The tungsten mineralization in concert with the gold is the odd-ball occurrence "During World War Two you could conduct your military service here at Stibnite mine
