Abstract

Process for the reduction of metal oxide(s), preferably in the form of pellets, by heating such in the presence of a solid reducing agent, e.g. pit-coal, in a retort (S) and causing the gaseous reaction product(s) to move at least partially in co-current flow with the direction of flow of the charge (K). An apparatus for carrying out the process comprising at least one retort (S) which has an inlet (25, 26) at the top for admission of the charge (K), an outlet (36, 37) at the bottom of the retort (S) for discharge of the spent charge (K) and a gas outlet (33, 20), separate from the outlet (36, 37), at the bottom of the retort for discharge of gas(es). <IMAGE>
