Abstract

Se refiere a un metodo para deshidratar una suspension de mineral acuoso que comprende introducir en la suspension, un sistema de floculacion que comprende un copolimero de poli (oxido de etileno), en particular un copolimero de oxido de etileno y uno o mas monomeros de glicidil eter de silano o siloxano funcionalizado. Los copolimeros de poli (oxido de etileno) son utiles para el tratamiento de suspensiones de material particulado, especialmente suspensiones minerales residuales. Es particularmente apropiada para el tratamiento de colas y otro material residual que resulta del procesamiento mineral, en particular, el procesamiento de colas de arenas pertroliferas
