Zinc metal is deposited on mobile seed particles in an electrowinning process. Exceptionally favorable results in terms of production rate, current efficiency and energy consumption are achieved by using a unique combination of design parameters and operating conditions achieved by selected ranges for particle size, current density, particle bed thickness, and acid content of the electrolyte.
Un procédé d'extraction électrolytyque consiste à déposer du zinc sur des particules germes mobiles. On obtient des résultats exceptionnels en matière de cadence de production, de rendement en courant et de consommation d'énergie en utilisant une combinaison unique de paramètres de calcul et de conditions d'utilisation atteints grâce à un éventail sélectionné de taille des particules, de densité de courant, d'épaisseur du lit de particules et de teneur en acide de l'électrolyte.
