A process for producing liquid smelting iron in an electric arc furnace includes several electrodes, equipped with a hearth, and containing a heel covered with a non-foaming liquid slag. The process further includes the reduction of the metallic fines, in order to form pre-reduced metallic fines containing an excess of free carbon; the hot transfer of the pre-reduced metallic fines within a curtain of inert gas into the heel contained in the electric arc furnace; the agitation of the heel by the injection of gas in such a manner that the formation of crusts is avoided; and the smelting of the pre-reduced metallic fines in the electric arc furnace in order to obtain the liquid smelting iron.
