Abstract

PROCESSO PARA LIXIVIAçãO APERFEIçOADA DE METAL NãO PRECIOSO E/OU URâNIO Um processo para oxidação de um processo para lixiviação aperfeiçoada de metal não precioso e/ou urânio de minérios, concentrados ou lamas usando íon férrico como um agente oxidante. Um vaso de reação (10) contém uma solução contendo íon ferroso, por exemplo, uma lama de lixívia de sulfeto de cobre ou concentrado. Um agitador (12) pode ser provido para promover lixiviação do é injetado no reator (14) para facilitar a oxidaçco. A solução contendo íon férrico é então recirculada de volta ao vaso de reação (10) onde os íons férricos são reutilizados na dissolução de sulfeto de cobre em sulfato de cobre solúvel. Os dois processos, de oxidação ferrosa e lixiviação de metal, podem ser conduzidos simultaneamente ou seq³encialmente para efetuar a recuperação de cobre, outros metais não preciosos ou urânio de minérios, concentrados ou lamas.PROCESS FOR IMPROVED LEVELING OF NON-PRECIOUS METAL AND / OR URANIUM A process for oxidizing a process for improved leaching of non-precious metal and / or uranium from ores, concentrates or sludges using ferric ion as an oxidizing agent. A reaction vessel (10) contains a solution containing ferrous ion, for example, a copper sulfide bleach slurry or concentrate. An agitator (12) can be provided to promote leaching of what is injected into the reactor (14) to facilitate oxidation. The solution containing ferric ion is then recirculated back to the reaction vessel (10) where the ferric ions are reused to dissolve copper sulfide in soluble copper sulfate. The two processes, ferrous oxidation and metal leaching, can be conducted simultaneously or sequentially to recover copper, other non-precious metals or uranium from ores, concentrates or sludge.
