Abstract:
Method for the production of liquid metal from metal carriers (3) in a melter gasifier (1) in which with supply of a carbon-containing material at least partially formed of fine coal (16) and coal dust (13) and with supply of oxygen or oxygen-containing gas the metal carriers are melted in a bed (4) of the carbon-containing material with the simultaneous formation of a reducing gas, optionally upon previous final reduction, characterized in that fine coal (16) and coal dust (13) are mixed with hot bitumen (20) and subsequently are cold-briquetted, and that the briquettes (25) thus formed are charged to the melter gasifier (1) and in the melter gasifier (1) are subjected to shock-heating, and wherein the charged carbon-containing material is dried and during and/or after drying of the carbon-containing material, the fine coal (16) and coal dust (13) are separated from lumpy carbon-containing material and further treated while hot.
