ABSTRACT:
In a combined process crude iron and a synthesis gas particularly suitable for the preparation of methanol are prepared by supplying iron ore concentrate to the plasma zone between an electrode and a crude iron melt in an arc furnace, while injecting gaseous or volatile hydrocarbons, for example natural gas mainly consisting of methane, into the crude iron melt.
