In contrast to the blast furnace process the direct reduced iron process operates at temperatures of up to 1000 °C The iron ores are therefore not melted This also applies to the gangue contained in the ore which is why the iron ores used must be relatively low in gangue from the outset The reduction gases only dissolve oxygen from the
