Abstract
a presente invenção refere-se à metalurgia de terras raras, em particular ao método para recuperação de escândio a partir de lama residual que é deixada como subproduto da produção de alumina. o método inclui reformação como polpa de lama residual, lixiviação com sorção do escândio da polpa da lama residual com uso de um agente de sorção de troca de íons para obter trocador de íons rico em escândio e polpa esgotada em escândio, a dessorção do escândio com uma solução de hidrocarbonato de sódio para obter trocador de íons dessorvido, que é retornado ao estágio de lixiviação com sorção do escândio e solução de escândio de recuperação industrial que é transferida para obter escândio concentrado por meio de deposição, caracterizado pelo fato de que é lixiviado com sorção continuamente da polpa da lama residual no trocador de íons contendo fósforo num modo em contracorrente em contato direto da polpa com trocador de íons, o escândio é dessorvido da fase orgânica do trocador de íons por solução de hidrocarbonato de sódio com concentração de na2co3 de 200 a 450 g/dm3 para obter escândio de recuperação industrial, a partir do qual um concentrado de escândio é recuperado. o efeito técnico da invenção consiste em melhorar o grau de recuperação do escândio da lama vermelha e a qualidade de uma recuperação industrial de escândio junto com redução dos custos.
