Stibnite, sometimes called antimonite, is a sulfide mineral, a mineral form of antimony trisulfide ( Sb 2 S 3). It is a soft, metallic grey crystalline solid with an orthorhombic space group. [6] It is the most important source for the metalloid antimony. [7]

Stibnite, also known as Antimonite, is an antimony sulfide mineral that crystallizes in the forms of masses, but is most commonly known when seen in it’s semi-rare, long prismatic crystal structure. These long, tubular crystals can be seen ranging from a few inches, to a few feet.

Sep 4, 2023 · Stibnite is a mineral composed of antimony sulfide (Sb2S3). It has a distinctive silvery-gray to lead-gray color and is known for its unique crystal structure. Here are some of its chemical, physical, and optical properties: Chemical Properties: Chemical Composition: Stibnite is composed of two elements, antimony (Sb) and sulfur (S).

Stibnite forms some of the most outstanding natural crystals that exist, in way of sharpness, luster, and size. It can form in groups of huge metallic lustered crystals that are elegantly crafted and exceptionally shiny. Stibnite is often replaced by dull yellow Stibiconite and Cervantite.

Lead-gray with pale blue tint. Stibnite Group. Renamed in 1832 by François Sulpice Beudant. According to Dioscorides, the original Greek names for the mineral were Στιβι "stibi", Στιμμι "stimmi", and Πλατνόπθαλμου "platnopthalmos". The former name became the Latin "stibium" and the old name for the element antimony (Sb).

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]).

Jun 13, 2018 · 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.

Jun 13, 2019 · Stibnite is an antimony trisulphide mineral with the chemical formula Sb2S3. It is a natural mineral source of the chemical element antimony (Sb), which is a lustrous grey metalloid, and it is mined primarily for this reason.

Stibnite or antimonite is sulfide metalloid mineral of antimony with chemical formula (Sb 2 S 3). The color is shiny lead-gray tarnishing to black with massive, granular, radiating, and elongated crystals habits (Fig. 1.50). The mineral contains 71.7% antimony in its natural purest form.

Name: From the Greek stibi, then Latin stibium, an old name for the mineral.
