Abstract

"PROCESSO PARA TRATAR BORRA CONTENDO UM METAL RECUPERáVEL E APARELHO PARA RECUPERAR UM METAL, TAL COMO ALUMìNIO, CONTIDO EM UMA BORRA". São descritos um processo e um aparelho para recuperação aperfeiçoada de metal a partir de uma borra, em que um forno de tratamento de borra é dotado de um revestimento ou parede refratária com boa capacidade de armazenar e conduzir calor. Este forno é preaquecido a uma temperatura desejada por injeção de oxigênio para queimar metal não recuperável que permanece no resíduo depois do vazamento do metal recuperável contido na borra. Quando a borra é tratada neste forno preaquecido, o calor que emana por condução a partir da parede do forno é suficiente para fundir e separar o metal recuperável contido na borra, sem adição de uma fonte de calor externa, tal como queimadores a combustível ou a gás, maçaricos de plasma ou arcos elétricos.
