Abstract
"MéTODO PARA PROCESSAMENTO DE áCIDO SULFúRICO CONSUMIDO CONTENDO FERRO". A presente invenção refere-se a um método para processamento de ácido sulfúrico consumido que contém metais pesados. Para isso, o ácido sulfúrico consumido contendo ferro ou materiais sulfúricos contendo ferro obtidos do mesmo são reagidos com um material que contém cloreto de ferro e, opcionalmente, outros cloretos metálicos, produzindo sulfato de ferro (II). Preferencialmente, o ácido sulfúrico consumido, é proveniente da produção de dióxido de titânio.
