Abstract

"RECUPERAçãO DO METAL A PARTIR DO SULFATO DE SóDIO E OUTRAS COMPOSIçõES". Um método para a recuperação de metal de alumínio a partir de blocos de tamanho variado de sulfato de sódio. Os blocos de sulfato de sódio têm concentrações variadas de metal de alumínio. O método inclui etapas de segregar (14) os blocos de tamanho variado em blocos menores e blocos maiores, por tamanho; separar (22), por concentração de metal de alumínio, os blocos maiores em blocos de maior concentração de metal de alumínio e blocos de refugo de menor concentração de metal de alumínio; causar impacto (24) nos blocos de refugo para reduzir no tamanho os blocos para blocos menores de refugo; retornar os blocos menores de refugo depois de causar impacto para a etapa prévia de segregar; segregar (20) os blocos menores da etapa de segregar em blocos grandes e blocos pequenos, por tamanho; separação (28), por concentração do metal de alumínio, dos blocos pequenos em blocos de maior concentração de metal de alumínio e segundos blocos de refugo de menor concentração de metal de alumínio; e separar (30) os segundos blocos de refugo em blocos de maior e menor concentração de alumínio.
