The sulphur burns to SO2, which is partly converted by the heated quartz, c., into SO3, uniting with the free oxygen present. The ferrous sulphate formed by this sulphuric acid is split up by the heat and the ferrous oxide (FeO) converted into ferric oxide (Fe2O3) which gives the ore a red colour when cold.
