Abstract

LA PRESENTE INVENCIÓN SE RELACIONA CON UN MÉTODO PARA DESHIDRATAR UNA SUSPENSIÓN DE MINERAL ACUOSO QUE COMPRENDE INTRODUCIR EN LA SUSPENSIÓN, UN SISTEMA DE FLOCULACIÓN QUE COMPRENDE UN COPOLÍMERO DE POLI(ÓXIDO DE ETILENO), EN PARTICULAR UN COPOLÍMERO DE ÓXIDO DE ETILENO Y UNO O MÁS MONÓMEROS DE GLICIDIL ÉTER DE SILANO O SILOXANO FUNCIONALIZADO. LOS COPOLÍMEROS DE POLI(ÓXIDO DE ETILENO) SON ÚTILES PARA EL TRATAMIENTO DE SUSPENSIONES DE MATERIAL PARTICULADO, ESPECIALMENTE SUSPENSIONES MINERALES RESIDUALES. LA INVENCIÓN 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 PETROLÍFERAS.THE PRESENT INVENTION IS RELATED TO A METHOD FOR DEHYDRATIONING A SUSPENSION OF A WATER MINERAL THAT INCLUDES INTRODUCING IN THE SUSPENSION, A FLOCULATION SYSTEM THAT INCLUDES A POLYOL POLYMER (ETHYLENE OXIDE), IN PARTICULAR OR A COPY OF ONE OR MORE THAN ONE COPOL SILICON OR SILOXANE FUNCTIONALIZED GLICIDIL Ether MONOMERS. POLY COPOLYMERS (ETHYLENE OXIDE) ARE USEFUL FOR THE TREATMENT OF SUSPENSIONS OF PARTICULATED MATERIALS, ESPECIALLY RESIDUAL MINERAL SUSPENSIONS. THE INVENTION IS PARTICULARLY APPROPRIATE FOR THE TREATMENT OF TAILS AND OTHER RESIDUAL MATERIAL THAT RESULTS FROM THE MINERAL PROCESSING, IN PARTICULAR, THE PROCESSING OF TAILS OF OIL SANDS.
