Abstract
In a process for the production of a metal melt in a metallurgical vessel, the filter dusts incurring in producing the metal melt are to be processed to charging substances without causing a load on the environment and without great expenditures. This is achieved in that the filter dusts are introduced into the metallurgical vessel by aid of a gaseous conveying medium composed of natural gas or a mixed gas primarily containing natural gas, the filter dusts being supplied to the metallurgical vessel in a closed system and reduced by the carrier gas.
