Abstract
L'invention concerne l'industrie de l'hydrométallurgie. Procédé de purification du nickel par chloration sous une couche de chlorure de métal alcalin fondu dans lequel se dissolvent les chlorures formés avec les impuretés; le sel solidifié, chargé des impuretés, est purifié par lixiviation, pendant une durée inférieure ou égale à 10 mn, avec une solution aqueuse saturée par le chlorure de métal alcalin, contenant aussi au moins 50 g/l de chlorure de nickel. Application à la purification de mattes de nickel contenant comme impuretés un ou plusieurs des éléments Fe, Cu, Co, Pb, Cr, Zn, Mn, Cd ou Sn.The invention relates to the hydrometallurgical industry. A method of purifying nickel by chlorination under a layer of molten alkali metal chloride in which the chlorides formed with the impurities dissolve; the solidified salt, loaded with impurities, is purified by leaching, for a period of less than or equal to 10 min, with an aqueous solution saturated with the alkali metal chloride, also containing at least 50 g / l of nickel chloride. Application to the purification of nickel mattes containing as impurities one or more of the elements Fe, Cu, Co, Pb, Cr, Zn, Mn, Cd or Sn.
