Problem When Roasting Iron From Antimony Ore
Iron perchloride, formed quite early in the roasting, is volatile, and some of it flies away, while another part, giving off chlorine, is reduced to proto-chloride, and this again, losing the remaining chlorine, takes oxygen from the air, and forms iron peroxide, which remains in the ore.

Roasting Arsenic & Antimony Ores
By raising the temperature sulphates are decomposed, but arseniates and antimoniates are stable at high temperatures and cause loss of silver in the fusion. To prevent their formation the ore should be roasted in a coke furnace, starting to heat it very gradually and admitting a limited supply of air.

Extraction of Antimony
For roasting sulphide ores two methods are used, viz., simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide. In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed.
Antimony Smelting - Mineral Processing & Metallurgy
China 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 ...

However, this “burning” or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted. Exact temperatures used in roasting vary, and excessive temperatures can cause problems, including melting the sulfides before they can oxidize.

How to Remove Arsenic, Antimony & Bismuth from Copper
In roasting copper, the removal of arsenic and antimony proceeds with notably greater rapidity after the copper has become dry (i.e., when it is saturated with cuprous oxide) than when it still contains appreciable quantities of iron and sulphur.
Antimony (Element) | Infoplease
Antimony is often found in other ores as well, e.g., silver, copper, and lead. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron; often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony …
