Abstract

MéTODO DE PREPARAçãO E TRATAMENTO DE CONCENTRAçãOS DE NìQUEL A invenção se refere a um método para preparação e tratamento de concentrados sulfídicos de níquel de difícil processamento, ricos em diversos silicatos de magnésio. De acordo com a invenção, a influência adversa dos silicatos de magnésio é aliviada fazendo-se uso da sua solubilidade. A exeqüibilidade de um concentrado para processamento é, dessa forma, melhorada e se obtém um concentrado que é mais adequado para um tratamento pirometalúrgico e hidrometalúrgico.
