Title
(EN) METHOD OF PRODUCING METAL
(FR) PROCÉDÉ DE PRODUCTION DE MÉTAL
Abstract
(EN)
A method of producing a non-metallic feedstock powder suitable for reduction to metal comprises the steps of combining a liquid with solid metal oxide particles to form a mixture, subjecting the mixture to high-shear mixing to form a liquid suspension of metal oxide and the liquid, and drying the liquid suspension using a fluidised-bed spray-granulation process to grow a plurality particles to form the non-metallic feedstock powder. The method allows feedstock powders to be grown to desired particle sizes. The method allows production of feedstock powders having controlled compositions.
(FR)
L'invention concerne un procédé de production d'une poudre de charge de départ non métallique appropriée pour la réduction en métal, comprenant les étapes consistant à combiner un liquide avec des particules d'oxyde métallique solide pour former un mélange, soumettre le mélange à un mélange sous cisaillement élevé pour former une suspension liquide d'oxyde métallique et du liquide et sécher la suspension liquide à l'aide d'un processus de granulation par pulvérisation en lit fluidisé pour faire croître une pluralité de particules pour former la poudre de charge de départ non métallique. Le procédé permet de faire croître des poudres de charge de départ à des tailles des particules souhaitées. Le procédé permet la production de poudres de charge de départ ayant des compositions régulées.
