PCT No. PCT/EP92/00551 Sec. 371 Date May 3, 1993 Sec. 102(e) Date May 3, 1993 PCT Filed Mar. 13, 1992 PCT Pub. No. WO92/16663 PCT Pub. Date Oct. 1, 1992.In a process and an apparatus for the production of liquid metal (4) from fine-grain metal oxide particles, the particles, together with hot reducing gas, are blown against a heated bulk material filter layer (9) of lump coal and/or ceramic pieces, a substantial proportion of the particles being retained on and in the filter layer and subjected to finishing reducing by the reducing gas. A high-temperature flame is produced in front of the filter layer (9) by an oxygen-bearing gas being blown against the filter layer, and the metallised particles which are retained in the filter layer are melted. They pass in the liquid condition through the filter layer (9) into a receiving space (3) for liquid metal (4).
