- Antimony Ore To Antimony Oxide
The average price for antimony metal quoted by the London Metals Exchange during 1992, was about US$1690 per tonne, whereas antimony ore (60%) averaged US$15.75. World Occurrence and Production World mine production of antimony metal is about 60 000 tonnes (t) a year (63,800 t Sb contained in ores and concentrates in 1992; Masters, 1993).

Reduction: The antimony oxide is then reduced to metallic antimony by heating it with carbon or by reacting it with iron scrap in a blast furnace. Refining: The crude antimony is further refined to remove impurities. This is typically done through ...

Antimony is traded in several forms such as ores and concentrates, antimony xide (ATO), unwrought antimony metal and powders, and scrap. As halogenated antimony xide is still highly used as an effective flame retardant, ATO is likely to remain the principal market for antimony in the EU. The continued use of ATO
