Abstract

Fremgangsmåte for utvinning av metaller eller metallforbindelser fra metallholdige, faste partikler innbefattende flyktige forbindelser innbefattende tilførsel av de faste partiklene (50) gjennom en flamme (25) i en brenner (20). De flyktige forbindelsene fordampes deretter ved hjelp av varme fra flammen (25) mens den opprinnelige formen og aggregattilstanden av de faste partiklene opprettholdes, som derved tilveiebringer et råmaterialeprodukt (34). Råmaterialproduktet (34) blir deretter utvunnet. Ved mating av de faste partiklene direkte til flammen, tilveiebringes et kompakt og effektivt anlegg. Smelteprosessen kan kontrolleres på en tilfredsstillende måte, som unngår smelting av de metallholdige, faste partiklene tilført gjennom brenneren. Anvendelsen av en brenner er også beskrevet. ?? ?? ?? ?? 1A method for recovering metals or metal compounds from metal-containing solid particles including volatile compounds including supply of the solid particles (50) through a flame (25) in a burner (20). The volatiles are then evaporated by heat from the flame (25) while maintaining the original shape and aggregate state of the solid particles, thereby providing a raw material product (34). The raw material product (34) is then recovered. By feeding the solid particles directly to the flame, a compact and efficient system is provided. The melting process can be controlled satisfactorily, which avoids melting of the metal-containing solid particles supplied through the burner. The use of a burner is also described. ?? ?? ?? ?? 1
