Abstract

um método de recuperação de magnetita a partir de resíduo de bauxita (62), compreendendo a redução de ph (63) do resíduo de bauxita (62) para formar um resíduo de bauxita tratado, secar (64) o resíduo de bauxita tratado, adicionar a e misturar (65) no resíduo de bauxita tratado uma fonte sólida de carbono (66), para criar uma mistura, aquecer a mistura para uma temperatura de redução de pelo menos 800°c em um reator de redução (67) para produzir um resíduo de bauxita reduzido, no qual uma parte principal de fe2o3 presente no resíduo de bauxita tratado foi convertido em fe3o4 expondo o resíduo de bauxita reduzido a uma etapa de separação de partículas (71), e então separando (72) o resíduo de bauxita reduzido em uma parte enriquecida com ferro (73) e uma parte exaurida de ferro (74).
