Abstract
The invention relates to a process and an associated apparatus for producing metals and/or primary metal products, in particular pig iron and/or primary pig iron products, in which a metal-containing charge material, in particular in fine particle form, is introduced, using pneumatic conveying, by means of a carrier gas stream, in the form of a stream of medium formed from the charge material and the carrier gas stream, into a melting unit, in particular a melter gasifier, for further processing. According to the invention, the charge material is introduced after the carrier gas stream has been separated off and separately at at least two introduction points, so that at least two partial quantities of the charge material can be introduced independently of one another and continuously or in stacked form.
