Abstract
MÉTODO DE RECUPERAÇÃO DE ZINCO METÁLICO A PARTIR DE RESÍDUOS METALÚRGICOS SÓLIDOS. A presente invenção refere-se a um método para recuperação de zinco metálico a partir de um resíduo metalúrgico sólido que contém zinco e manganês, que compreende as etapas de: a. colocar o dito resíduo metalúrgico sólido em contato com uma solução aquosa de lixiviação que compreende íons de cloreto e íons de amônio para produzir pelo menos um lixiviado que compreende íons de zinco e íons de manganês e pelo menos um resíduo sólido insolúvel; b. cimentar o dito lixiviado, adicionando zinco metálico como um agente precipitante, para eliminar pelo menos um metal diferente de zinco e manganês possivelmente presente no dito lixiviado na forma de íons e produzir um lixiviado purificado; c. submeter o dito lixiviado purificado a eletrólise em uma célula eletrolítica que compreende pelo menos um cátodo e pelo menos um ânodo imerso no dito lixiviado purificado para depositar zinco metálico no dito cátodo e produzir pelo menos um lixiviado esgotado; em que o dito método compreende, antes da dita eletrólise, uma etapa de precipitação de íons de manganês por oxidação com íons de permanganato e subsequente separação de um precipitado que compreende MnO2.
