Abstract

"MéTODO PARA REMOçãO DE CáLCIO DE UMA SOLUçãO DE SULFATO EM UM PROCESSO DE PRODUçãO DE ZINCO". A presente invenção se refere a um método para remoção de cálcio de uma solução de sulfato em um processo de produção de zinco. O cálcio é removido na forma de um anidrato da solução bruta proveniente da etapa de lixiviação do concentrado ou minério, antes dos estágios de purificação da solução.
