Title: Procede pour separer le zinc, le fer, le calcium, le cuivre et le manganese des solutions aqueuses de cobalt et/ou de nickel
Inventor: LINDELL ESA
IPC: C22B3/42
Filed: 2009-02-18
Abstract: La présente invention concerne un procédé pour séparer le zinc, le fer, le calcium, le cuivre et le manganèse des solutions aqueuses de cobalt et/ou de nickel. Une solution aqueuse (1) contenant des sels métalliques est amenée en contact avec une solution d'extraction (2) pour former un mélange. Cette solution a préalablement reçu une charge d'ions de cobalt et/ou de nickel. Le cobalt et/ou le nickel de la solution d'extraction sont remplacés par les métaux d'impureté, la solution aqueuse étant ensuite nettoyée de ses impuretés. Cette solution aqueuse purifiée, c'est-à-dire le raffinat (3), convient pour constituer la charge préalable en ions de cobalt et/ou de nickel de la solution d'extraction, de façon à mettre une petite partie (5) du raffinat en contact avec une solution d'extraction préalablement neutralisée (6). Le cobalt et/ou le nickel viennent ainsi remplacer l'ion de métal alcalin, de métal alcalino-terreux ou d'ammonium qui est utilisé pour la neutralisation préalable. Après cette opération de charge préalable, la solution aqueuse contenant ledit ion de métal alcalin, de métal alcalino-terreux ou d'ammonium, mais ne contenant pas de cobalt ni de nickel, est éliminée du processus comme rejet (7). Après l'opération d'extraction, la solution d'extraction (8) peut être lavée au cours d'une opération distincte de lavage avec de l'eau de lavage (9) qui contient des chlorures des métaux d'impureté. Dans ce cas, les ions de cobalt et/ou de nickel subsistant dans la solution d'extraction sont remplacés par les ions d'impureté et transférés à la solution aqueuse contenant les chlorures. Cette eau de lavage (11) peut être envoyée à l'opération de charge préalable précédente, les ions de chlorures entraînés étant éliminés comme rejets. Après l'opération de lavage, les impuretés peuvent être extraites en retour dans la solution aqueuse par la solution aqueuse (13) d'acide chlorhydrique.

Abstract: In a hot isostatic pressing process or hot uniaxial pressing process for producing a net or near net shape product, a diffusion filter comprising boron nitride is provided between a graphite former and metal powder to be pressed thereagainst. The diffusion filter allows a controlled amount of carbon to diffuse into the surface of the pressed component. The boron nitride is conveniently applied as an aqueous slurry by spraying. In order to obtain adherence between the coating and the surfaces of the former, one or more thin ghost coat layers of slurry are applied to the surface of the graphite former before one or more layers of normal strength slurry are applied. Each layer of coating is allowed to dry before the next layer is applied, and the former may be heated to dry each layer. Pressed components of length greater than 2m can be processed, relative contraction of the component and former during cooling of the component being accommodated by the boron nitride coating on the former. The thickness of the coating can be determined by trials to achieve a controlled diffusion of carbon into the surface of the pressed component, and the dimensions of the former chosen to accommodate that thickness of coating.
