roasting iron from antimony ore

EiC July 2008 - Feature - Antimony revisited. 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.
