Abstract

método e sistema para refino anódico de cobre, e, métodos para refino contínuo de cobre em um forno de anodo, e para inibir a formação de nox durante refino de metais. são providos um método e sistema para refino anódico de cobre nos quais tecnologia de jato coerente é empregada para aquecer cargas de cobre empolado fundido e/ou sucata fundida usando uma chama de fusão, oxidar o enxofre no cobre empolado fundido e reduzir o oxigênio no cobre empolado fundido usando correntes de gás de jato coerente de sopro por cima de um ou mais conjuntos de lança de jato coerente multifuncionais . os presentes sistemas e método empregam um controlador a base de microprocessador que controla operacionalmente o fluxo de um gás contendo oxigênio, um gás inerte, e um agente redutor e um combustível para a lança de jato coerente. o sistema e método de refino anódico de cobre revelados melhoram bastante a produção de cobre, reduzindo ainda os tempos de ciclo de oxidação/redução e minimizando emissões de nox.
