Abstract

processo para a separação de pelo menos um metal de uma escória, e, uso de pelo menos uma partícula magnética. a presente invenção refere-se a um processo para a separação de pelo menos um metal de uma escória, compreendendo aquele pelo menos um metal e outros componentes, compreendendo pelo menos a etapa (a) de moer a escória (b) se apropriado, contatar a escória moída de etapa (a) com pelo menos uma substância tensoativa e/ou pelo menos uma partícula magnética,s e apropriado na presença de pelo menos um dispersante, resultando na formação de aglomerados de o pelo menos um metal e a pelo menos uma partícula magnética, (c) se apropriado, adicionar o pelo menos um dispersante na mistura obtida em etapa (b) para obter uma dispersão tendo uma concentração adequada, e (d) separar os aglomerados da mistura de etapa (b) ou (c) por aplicação de um campo magnético, e ao uso de pelo menos uma partícula magnética para a separação de escória.process for separating at least one metal from a slag, and using at least one magnetic particle. The present invention relates to a process for separating at least one metal from a slag comprising that at least one metal and other components, comprising at least the step (a) of grinding the slag (b) if appropriate, contacting the invention. the ground slag from step (a) with at least one surfactant and / or at least one magnetic particle, if appropriate in the presence of at least one dispersant, resulting in the formation of agglomerates of at least one metal and at least one particle. (c) if appropriate, add at least one dispersant to the mixture obtained in step (b) to obtain a dispersion having a suitable concentration, and (d) separate the agglomerates from the mixture of step (b) or (c) by application of a magnetic field, and the use of at least one magnetic particle for slag separation.
