Abstract
UN PROCESO PARA EL TRATAMIENTO DE LICORES ACIDOS ACUOSOS QUE CONTIENEN COMPUESTOS DE ALUMINIO Y/O HIERRO DISUELTOS PARA PRODUCIR UN PRODUCTO DE TRATAMIENTO DE AGUAS DE ALUMINIO Y/O SULFATO DE HIERRO SE CARACTERIZA POR LA COMBINACION DE PASOS QUE COMPRENDE PONER EN CONTACTO EL LICOR CON UN MATERIAL BASICO CAPAZ DE REACCIONAR CON EL COMPUESTO DE ALUMINIO Y/O HIERRO DISUELTO PARA PRECIPITAR VALORES DE ALUMINIO Y/O HIERRO, SEPARACION DEL PRECIPITADO EN LA FORMA DE UN PASTEL O PASTA AGUADA A PARTIR DEL LICOR RESTANTE, TRATAMIENTO DEL PASTEL O PASTA AGUADA CON ACIDO SULFURICO PARA VOLVER A DISOLVER VALORES DE ALUMINIO Y/O HIERRO Y PARA PRODUCIR UNA SOLUCION DE ALUMINIO Y/O SULFATO DE HIERRO Y SEPARACION DE LA MATERIA SOLIDA SUSPENDIDA DE LA SOLUCION. EL LICOR PUEDE SER UN PRODUCTO RESIDUAL DE PROCESOS INDUSTRIALES O PUEDE SER UN EFLUENTE DE MINA Y EL PROCESO EVITA LA NECESIDAD DE ELIMINARLOS PARA RESIDUOS. DONDE EL LICOR SE DERIVA DE LA ACTIVACION ACIDA DE UN MINERAL ALUMINOSILICEO, EL PRODUCTO CONTIENE SILICE DISUELTO, Y SE PRODUCE COMO UN SUBPRODUCTO UNA CUALIDAD SUSTANCIAL DE UN AGENTE BLANQUEANTE DE ACEITE. EL PRODUCTO PUEDE MEZCLARSE CON UN POLIMERO CATIONICO DE BAJO PESO MOLECULAR PARA PROPORCIONAR UN RENDIMIENTO DE FLOCULACION MEJORADO.
