Abstract

Patente de Invenção: <B>"PROCESSO PARA CONVERTER METAL NãO-FERROSO, TAL COMO COBRE OU NìQUEL, POR MEIO DE ENRIQUECIMENTO COM OXIGêNIO"<D>. Um processo para a conversão de mate de cobre ou níquel compreendendo uma quantidade em peso substancial de um material à base de ferro. Durante uma primeira etapa do processo, substancialmente todo o material à base de ferro é oxidado com um gás compreendendo oxigênio para produzir óxido ferroso que é, em seguida, transformado em escória pela adição de um material sólido ao metal fundido. Em seguida, em uma segunda etapa do processo, o material à base de cobre é oxidado com o referido gás compreendendo oxigênio para gerar cobre substancialmente puro e resíduos. O gás compreendendo oxigênio é injetado através de um injetor interno de uma tubeira protegida concentricamente. Um gás de proteção substancialmente inerte é injetado através da passagem de gás entre o injetor interno e o externo.
