Abstract
SE DESCRIBE UN PROCESO PARA AGLOMERAR POR EXTRUSION SUBPRODUCTOS METALURGICOS Y PRODUCTOS DE DESECHO QUE TIENEN UN TAMAÑO DE PARTICULA PEQUEÑO. UNA MEZCLA DE SUBPRODUCTOS METALURGICOS, ALGUNOS DE LOS CUALES CONTIENEN SILICATOS YA TRATADOS A ALTAS TEMPERATURAS Y QUE POR TANTO SON CAPACES DE UNIRSE QUIMICA Y ESTRUCTURALMENTE AL AGUA, OPCIONALMENTE MEZCLADOS CON CEMENTO PORTLAND Y/O CEMENTO DE ESCORIA, Y QUE CONTIENEN AGUA QUE SE HA AÑADIDO EN CANTIDADES QUE LOS SILICATOS Y EL CEMENTO PRESENTES PUEDAN ABSORBER COMPLETAMENTE Y REACCIONAR CON ELLA, SE SIGUE MEZCLADO CON UNA SUSTANCIA HIDROCARBONACEA. A CONTINUACION SE AGLOMERA LA MEZCLA RESULTANTE MEDIANTE EXTRUSION. LOS PRODUCTOS EXTRUIDOS OBTENIDOS RETIENE SU FORMA Y SON LO SUFICIENTEMENTE DUROS COMO PARA PODER SER MANIPULADOS SIN QUE SE ROMPAN, NI DESMORONEN, NI LEVANTEN POLVO, Y SE PUEDEN CARGAR EN INSTALACIONES PIROMETALURGICAS EXTRACTIVAS PARA RECUPERAR LOS METALES DE VALOR QUE SE ENCUENTRAN EN LOS SUBPRODUCTOS METALURGICOS Y EN LOS PRODUCTOS DE DESECHO. LOS PRODUCTOS EXTRUIDOS TAMBIEN SE PUEDEN GUARDAR SIN QUE LEVANTEN POLVO NI PIERDAN SU DUREZA.
