7 common types of antimony ore

Antimony ores (Sb) exist in various mineral forms. Below are the common types of antimony ores: 1. Stibnite (Sb₂S₃): Description: The most important antimony ore, containing about 71.4% antimony by weight. Characteristics: Silver-gray color with a metallic luster, often found in columnar crystals or granular masses. Occurrence: Commonly found in hydrothermal veins under low to moderate temperature conditions. 2. Valentinite (Sb₂O₃): Description: An oxide form of antimony, usually formed through the oxidation of stibnite. Characteristics: White or pale gray crystals with no metallic luster. Applications: Used in alloy production and as a flame retardant. 3. Senarmontite (Sb₂O₃): Description: A polymorph of antimony oxide (Sb₂O₃). Characteristics: White cubic crystals. Occurrence: Rarer than valentinite and often found in weathered zones. 4. Cervantite (Sb₂O₄): Description: An oxidized antimony mineral. Characteristics: Yellow to orange-yellow color, often found in weathered zones of antimony veins. 5. Tetrahedrite (Cu₁₂Sb₄S₁₃): Description: A mixed ore containing copper and antimony. Characteristics: Gray to silver color with metallic luster. Occurrence: Found in hydrothermal veins alongside stibnite. 6. Jamesonite (Pb₄FeSb₆S₁₄): Description: A sulfide mineral containing lead, iron, and antimony. Characteristics: Silvery-gray color with metallic luster, occurring in fibrous or granular forms. Occurrence: Associated with sulfide-rich hydrothermal veins. 7. Kermesite (Sb₂S₂O): Description: A rare oxy-sulfide mineral of antimony. Characteristics: Dark red or reddish-brown color with a metallic sheen. Occurrence: Typically found in weathered zones of antimony-bearing ores. Summary The most common antimony ores are stibnite (Sb₂S₃) and oxide forms such as valentinite and senarmontite. Other ores like tetrahedrite and jamesonite contain antimony but are not primary sources for its extraction. #Antimonyore, #antimony, #ore
