Stibnite
Stibnite. Stibnite (antimony sulphide) is the main ore mineral of the metal antimony. Small amounts of antimony minerals were found in many Cornish mines but only a few were worked for antimony. Fewer still tried to produce it as their single main product. Most of these mines were in the north of the county.

Antimony | Geoscience Australia
Antimony is rarely found in its pure state and most commonly occurs in nature as the sulphide mineral stibnite (Sb 2 S 3). It also occurs in more than 100 other minerals, usually as oxide, e.g., valentinite (Sb 2 O 3 ), and as antimonies of heavy metal sulphides such as tetrahedrite ((Cu,Fe,Zn,Ag) 12 Sb 4 S 13 ), livingstonite (HgSb 4 S 7 ) …
Mineral Resource of the Month: Antimony
Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association with arsenic, bismuth or silver. The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals.

Member of: Arsenic Group. Name: From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being ...
Antimony: The mineral native Antimony information and …
The Mineral antimony. Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur. On a fresh or preserved surface, Antimony has a tin-white color with a slight blue tinge. Otherwise, it is dark gray due to tarnish.
Antimony
Many minerals contain antimony (Sb), a soft white metal with a low melting point. However, stibnite and antimonial lead ores are the main sources of the metal. Stibnite (Sb2S3) and stibiconite (Sb3+Sb25+O6(OH)) were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), a ...

Stibnite, or antimony trisulfide (Sb 2 S 3 ), is the most abundant of the roughly 100 antimony-bearing minerals. Antimony's chemical symbol (Sb) stems from stibium, the Latin word for stibnite. The origin of the word "antimony", however, is uncertain. One possibility is the 15th-century Middle English word antimonie, which …
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 …
