Abstract

I en fremgangsmåte for smelting av tungmetallholdige, spesi- elt Zn-holdige, stoffer (4), der stoffene (4) føres inn i en konverter eller rortorovn som tjener som smelteovn (1), og smeltes til slagg (10) av en brenner (2) som drives ved hjelp av en gass, som har en større oksygenandel enn luft, eller oksygen (6) og fossile brennstoff (5), hvorved det dannes røykgasser (7), drives brenneren (2) og/eller det flytende slagg (10) såpass reduktivt at Zn overføres til gassfasen, idet disse gassene forlater smelten og dermed blandes og føres ut med røykgassen (7). Dersom stoffene (4) som inneholder tungmetaller i tillegg inneholder Cu, tilfø- res slagget (10) flytende Fe-regulus (13) som bidrar til Cu- utarmingen. Tungmetallinnholdet i slagget (10) blir så lavt at slagget (10) underskrider de påkrevde grenseverdier for deponering.In a process for melting heavy metal-containing, especially Zn-containing, substances (4), wherein the substances (4) are fed into a converter or tube furnace serving as a melting furnace (1) and melted to slag (10) by a burner (2) operated by means of a gas having a higher oxygen content than air, or oxygen (6) and fossil fuels (5), thereby producing flue gases (7), the burner (2) and / or the liquid slag (10) so reductively that Zn is transferred to the gas phase, these gases leaving the melt and thus being mixed and discharged with the flue gas (7). If the substances (4) containing heavy metals additionally contain Cu, the slag (10) is added to liquid Fe regulus (13) which contributes to Cu depletion. The heavy metal content of the slag (10) becomes so low that the slag (10) falls below the required landfill limits.
