Abstract

PROCESSO DE LIXIVIAçãO NA PRESENçA DE áCIDO CLORìDRICO PARA A RECUPERAçãO DE UM METAL VALIOSO DE MINéRIO. A presente invenção descreve um processo para lixiviar um metal valioso de um minério contendo o referido metal valioso, o processo incluindo as etapas de lixiviar o minério na presença de ácido clorídrico para formar um sal de cloreto de metal solúvel em uma solução de lixívia; adicionar ácido sulfúrico à solução de lixívia; recuperar um sal de sulfato de metal da solução de lixívia; e regenerar o ácido clorídrico. O minério pode ser um minério de metal de base óxida, tal como um minério de óxido de zinco, um minério de níquel laterítico, tal como minério saprolítico ou limonítico; um minério de sulfeto ou um minério de titânio. O metal valioso é tipicamente selecionado do grupo que consiste em Zn, Cu, Ti, AI, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, metais do grupo da platina e ouro. O metal no sal de sulfato de metal pode ser o metal valioso, ou pode ser um metal de menos valor que o metal valioso, tal como magnésio. O ácido clorídrico regenerado é reciclado para o processo de lixiviação.
