During roasting the iron sulfides react with oxygen (in air or oxygen enriched air) to produce iron oxides (mainly as FeO, but with some magnetite (Fe 3O 4)) and sulfur dioxide. Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. The slag forming reaction is: FeO+SiO 2→FeO.SiO 2
