Stibnite: The mineral stibnite information and pictures

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.
Stibnite - The Bladed Crystals - mineralexpert.org

Stibnite is sometimes partially replaced by stibiconite Sb 3 O 6 (OH), a powdery oxide, and cervantite Sb 2 O 4, an antimony tetraoxide. If stibnite tarnishes, its coating may turn dull or iridescent. Excellent stibnite crystals from recent finds in China. Size 15 x 10 cm. Collection and photo: Albert Russ.
Antimony trioxide - Wikipedia

Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.

Stibnite: 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
Antimony trioxide - Wikipedia

Step 1) Crude stibnite is oxidized to crude antimony(III) oxide using furnaces operating at approximately 500 to 1,000 °C. The reaction is the following: 2 Sb 2 S 3 + 9 O 2 → 2 Sb 2 O 3 + 6 SO 2. Step 2) The crude antimony(III) oxide is purified by sublimation. Oxidation of antimony metal. Antimony metal is oxidized to antimony(III) oxide in ...
