Abstract

"PROCESSO DE CONCENTRAçãO DE WILLEMITA POR FLOTAçãO / REVERSA DE GANGA CARBONATADA". A presente invenção diz respeito a um processo de concentração de um minério silicatado de zinco, por meio da flotação reversa. Esta invenção referese ao processamento de minérios silicatados de zinco-willemíticos contendo ganga carbonatada, na forma de dolomita. A técnica conduz à produção industrial consiste na moagem e preparação de uma polpa de minério, condicionamento com reagentes que deprimam sificatos e outros que tornem hidrofóbicas as partículas de carbonatos e minerais de ferro, separando-os por flotação reversa. O produto final desta invenção destina-se ao processo hidrometalúrgico de obtenção do zinco metálico, que é iniciado com uma etapa de acidulação com ácido sulfúrico. As características de teor e recuperação de Zn do produto desta invenção são satisfatórios e adequados ao processo hidrometalúrgico, tendo sido obtido por meio de um processo de menor custo e menor impacto ambiental.
