Study on Extraction of Iron by the Short Circuit Reduction Method
短路还原法提取铁的研究

The zirconia,carbon and molten slags containing FeO were used to constitute a galvanic cell.The carbon-free metal could be directly obtained from molten oxide slags by the short circuit galvanic cell method.The following galvanic cell was assembled in the present experiment: graphite rod,O]_(Fe-C(saturated))|ZrO_2(MgO)|Cu_((1))+(FeO)_((slag)),Mo wire.Through measuring short circuit current by means of the electrochemical instrument,the electro-reduction reaction was studied by controlling factors such as temperature,the content of FeO,the external circuit resistance.The results showed that under the experimental conditions the reduction rate got larger with the elevation of temperature,the increase of FeO content and the decrease of the external circuit resistance.The actual final reduction ratio reached over 95%.A reduction method in the metallurgy with controlled oxygen flow was setup and the theory for metallurgy with controlled oxygen flow was developed.
