Zusammenfassung:	The invention relates to a method for roasting nickel sulphide produced by precipitation into nickel oxide in a fluidized bed furnace. The precipitated, very fine-grained nickel sulphide precipitateis micropelletized and the micropellet- ized precipitateis routed to fluidized bed treatment. Fluidized bed treatment may take place in a single fluidized bed furnace, in which there is a circulating fluidized bed,or in two fluidized bed furnaces in which there is a bubbling fluid- ized bed.
