Title (EN) METHOD FOR ROASTING NICKEL SULPHIDE
(FR) PROCÉDÉ DE GRILLAGE DU SULFURE DE NICKEL
Abstract: front page image
(EN)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.
(FR)Cette invention concerne un procédé de grillage du sulfure de nickel obtenu par précipitation en oxyde de nickel dans un four à lit fluidisé. Le précipité de sulfure de nickel précipité, à grains très fins, est micropastillé et le précipité micropastillé est acheminé vers un traitement en lit fluidisé. Le traitement en lit fluidisé peut s'effectuer dans un seul four à lit fluidisé, comportant un lit fluidisé de type à circulation, ou dans deux fours à lit fluidisé, comportant un lit fluidisé de type à barbotage.
