Abstract

PROCEDIMIENTO PARA MEJORAR LA CAPACIDAD DE BOMBEO DE LECHADAS ACUOSAS LE MINERALES FINALMENTE DIVIDIDOS, CONSTITUIDOS POR PARTICULAS QUE TIENDEN A SEDIMENTARSE DENTRO DE LA LECHADA CUANDO ESTA ES BOMBEADA. CONSISTE EN HACER REACCIONAR DICHA LECHADA, ANTES DE SU BOMBEO, CON UNA CANTIDAD COMPRENDIDA ENTRE 0,02 Y 0,4 POR 100 EN PESO, BASADA EN EL PESO DEL MATERIAL PRESENTE EN LA LECHADA, DE UNA SOLUCION ACUOSA DE UN AGENTE DISPERSANTE CONSTITUIDO POR UN COPOLIMERO DE UN MATERIAL HIDROFILO Y DE UN MATERIAL RELATIVAMENTE MENOS HIDROFILO, SIENDO LA PROPORCION DEL MATERIAL MENOS HIDROFILO DE UN 5 A UN 50 POR 100 EN PESO. EL AGENTE DISPERSANTE MAS UTILIZADO ES UN COPOLIMERO SOLUBLE EN AGUA DE ACIDO POLIACRILICO Y ACIDO POLIMETRACRILICO, CUYO PESO MOLECULAR ESTA COMPRENDIDO ENTRE 7.000 Y 8.000. DE USO EN LA MINERIA DEL CARBON, ESPECIALMENTE EN EL BOMBEO DE LECHADAS ACUOSAS DE COLAS O DESECHOS DE CARBON. D
