Abstract: A method for producing liquid pig iron (1), includes reducing iron-oxide-containing feed materials (2) to form a partially reduced first iron product (3) in a first reduction system (4), introducing the partially reduced first iron product (3), a first oxygen-containing gas (9, 9a), and a first carbon carrier (10) into a melter gasifier (11), introducing a second gaseous and/or liquid carbon carrier (13) and a second oxygen-containing gas (9b) into a mixing region (18) within the melter gasifier (11) above the fixed bed of the melter gasifier, mixing the second gaseous and/or liquid carbon carrier (13) with the second oxygen-containing gas (9b) in the mixing region (18), wherein the combustion air ratio is set in the range of 0.2 to 0.4, preferably between 0.3 and 0.
