Antimony lives in the neighbourhood of arsenic and shares similar traits not found alone'.2 Indeed, antimony is usually found as the sulfide ore, stibnite, Sb2S3, 250 years earlier.4 The process involved roasting stibnite to form the oxide, in which stibnite was reduced directly to metallic antimony by reaction with iron.

Roasting an overview ScienceDirect Topics

K.G. Thomas, A.P. Cole, in Gold Ore Processing (Second Edition), 2016 Abstract. Roasting of ores and concentrates can be defined as the heating of a material to cause reaction and the expelling of volatile matter without causing fusion. Oxidative roasting is used extensively to pretreat base and precious metal–bearing materials and to oxidize iron sulfides to generate sulfur dioxide for

2021-3-12  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
