Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.
Mineral Commodity Report 2 — Antimony by Tony Christie and Bob Brathwaite Institute of Geological and Nuclear Sciences Limited Discovery and Origin of Names Antimony was used as early as 4000 BC in containers, mirrors and bells. Stibnite, the major ore of antimony, was known and used in Biblical times as medicine and as a cosmetic for eyebrow ...
Stibnite, primarily a Sb 2S 3 ore that belongs to the orthorhombic system (a 0 ¼ 11.20 ˚A, b 0 ¼ 11.28 ˚A, and c 0 ¼ 3.83 ˚A), has been found as huge crystals and a crystal cluster (chemical purity: 99% Sb 2O 3) in many areas around the globe.25,26 In addition, stibnite is a signi cant raw mineral
DESCRIPTIVE MODEL OF SIMPLE Sb DEPOSITS By James D.Bliss and Greta J. Orris APPROXIMATE SYNONYM Deposits of quartz-stibnite ore (Smirnov and others,1983). DESCRIPTION Stibnite veins, pods, and disseminations in or adjacent to brecciated or sheared fault zones. GENERAL REFERENCES White (1962), Miller (1973). GEOLOGICAL ENVIRONMENT
As nouns the difference between ore and stibnite is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which—at the time of the rock's evaluation and proposal for extraction—are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values while stibnite is...
The store and post office were located at Stibnite. The mining process for tungsten and antimony during the War years originated at the Yellow Pine Mine where the tungsten ore body lay beneath a thick cover of gravel almost directly below the East Fork. The number one shaft was begun in April and the first tungsten ore was milled in August, 1941.
These include primarily conventional crushing and grinding followed by combined gravity concentration and flotation. First, as stibnite is the predominant mineral and China is the predominant producer, the industrial mineral processing of a typical Chinese stibnite ore will be elucidated.

Ores [edit | edit source]. In Omnifactory vanilla ores generate less frequently; instead most of them are found as GregTech Community Edition mixed veins. These veins come in four parts, with each part being a different ore and generate in ellipsoid shapes. The details as to how these ores generate are as follows: At the center of each 3x3 chunk section a specific vein type is chosen; if the ...
Stibnite, antimony sulfide (Sb2S3), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite
The stibnite-quartz geoenvironmental model is probably generally applicable to ore deposit models 27d, 27e, and 36c. The acid-buffering capacity of igneous rocks associated with some of these deposits is probably not significantly different from that of shale-hosted stibnite-quartz deposits. Key differences between stibnite-quartz veins and those

Used as a hardening alloy for lead, especially storage batteries and cable sheaths; also used in bearing metal, type metal, solder, collapsible tubes and foil, sheet and pipes and semiconductor technology. Antimony is used as a flame retardant, in fireworks, and in antimony salts are used in
Stibnite is the most important ore of the element antimony, and is an industrially important mineral. It was used as a metallic cosmetic in ancient civilization. Stibnite also forms some of the most exceptional crystal formations of all minerals, and large and well crystallized are highly sought after and appreciated by mineral collectors.

Public health effects of antimony. The Agency for Toxic Substances and Disease Registry has composed a comprehensive account of the public health effects of antimony, including health effects by route of exposure (inhalation, oral, and dermal exposure), toxicokinetics (absorption, distribution, metabolism, and excretion), biomarkers of exposure, and effect, among other chapters.
WHY THE CHINESE DOMINATE WORLD SUPPLY AND WHY THIS MAY CHANGE • The Chinese supply the world with more than 92%, or 350,000,000 ppy, of all the finished antimony products for four reasons: • First, China has had huge reserves of clean stibnite ore primarily in Hunan Province. • Second, they have dominated the metallurgy of antimony and at one time
ANTIMONY LEACHING FROM STIBNITE AND COMPLEX ORES1 Y.T. John Kwong2, Allen Pratt2 and Gianluigi Botton2 Abstract. To shed light on the leaching of Sb from mine wastes containing stibnite, two series of experiments were conducted. In one experiment, polished slabs of a museum-grade stibnite and a mixed-sulfide ore sample containing 28% Sb were
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 ...

Stibnite (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries. The metal also finds applications in solders and other alloys. Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations.
Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.
