Antimony is a silvery-white metal that is found in the earth''s crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony trioxide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1) Read More

The smelter started Oct with 37,665 lbs of crude oxide and 86,842 lbs of crude antimony metal. By Nov. 1, the entire stock of crude oxide had been converted to crude metal resulting in an inventory of 127,000 lbs of crude antimony metal. Thompson Falls: 30.5 tons of refined antimony trioxide were produced and sold in October.

Antimony oxide can be prepared by two processes, the direct and the indirect process. Indirect process. In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder. Read More

The wet method involves generating antimony trichloride by leaching sulfur antimony ore with hydrochloric acid and then hydrolyzing it with caustic soda. Crude stibnite is oxidized to crude antimony(III) oxide in furnaces that operate at temperatures ranging from 500 to 1,000 degrees Celsius. The reaction is the following:

Antimony trioxide, also called antimony white, has the formula Sb203 with a structure dependant on the temperature. It is used as a flame retardant, pigment, and catalyst. Antimony trioxide is mainly produced via the smelting of stibnite ore, which is oxidized to crude Sb2O3 using furnaces operating at approximately 850 to 1,000 °C.
