Abstract:
1. A method for producing a metal or a primary metal product, the method comprising: pneumatic conveying a stream including a carrier gas and a charge material comprising fine metal-containing particles; dividing the stream into at least two partial streams, each stream comprising a respective quantity of charge material; separating off the carrier gas from each of the at least two partial streams; and introducing at a first introduction point of a melting unit the charge material from a first stream of the at least two partial streams and introducing, independently of the introducing of the charge material of the first stream, the charge material from a second stream of the at least two partial streams at a second introduction point of the melting unit; effecting control at the dividing of the stream of the quantity of charge material carried by each of the at least two partial streams by controlling the separating off of the carrier gas for each of the at least two partial streams prior to the introducing of the charge material.
