The present invention relates to a process for the production of mineral fibres and to an apparatus which can be used in such a process. In particula r, the process of the present invention comprises: providing a furnace; char ging to the furnace mineral materials which comprise iron oxides; melting th e charged mineral materials in a reducing atmosphere, such that there is a b ase zone in the furnace in which molten iron collects, and a melt pool above the base zone where mineral melt collects; removing mineral melt from the f urnace and converting it to mineral fibres; and removing molten iron from th e base zone; characterised in that, during the process, an additive is relea sed directly into the base zone of the furnace wherein the additive comprise s one or more substances selected from oxidising agents and non-reducing gas es.
