Roasting Arsenic & Antimony Ores

The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore, 1 A.T. ; red lead, 1,000 grains; sodium carbonate, 500 grains; potassium ferrocyanide, 550 grains, with a cover of salt or borax.

antimony 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

Oxidative roasting is the process of converting metallic compounds in waste materials into oxides using oxidants. The aim is to obtain oxides to facilitate the next step of smelting. Oxidation roasting is often used in sulfide ore smelting. It is used to remove the sulfur ore, arsenic, antimony, and other harmful impurities in ore.
