How is it used? In Canada, antimony trioxide is primarily used in combination with other compounds to provide flame retardant properties. Flame retardants used in household items such as mattress covers, furniture and carpets may contain antimony trioxide.

Extraction of Antimony

The production of "secondary antimony" (i.e. the recovery of antimony from alloys and residues) forms an important means of obtaining the metal. In the United States of America in 1928, between 170,000 and 180,000 tons of old lead accumulators containing 3 per cent, antimony were available.Antimony SmeltingChina now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world's production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for ...Improved Smelting and Refining Processes for Production of ...Traditional smelting methods have been improved since the 1940s, but several novel achievements have been introduced in recent years.
