Abstract
<p>LA INVENCIÓN DA A CONOCER UN AGENTE LIXIVIADOR Y UN MÉTODO DE IIXIVIACIÓN PARA LIXIVIAR UNA TIERRA RARA EN UN MINERAL DE TIERRA RARA CON ABSORCIÓN IÓNICA. EL AGENTE LIXIVIADOR ES UNA SOLUCIÓN ACUOSA QUE COMPRENDE IONES REDUCTORES. UNA TIERRA RARA CON ABSORCIÓN IÓNICA ES LIXIVIADA POR UNA SOLUCIÓN ACUOSA QUE COMPRENDE IONES REDUCTORES COME AGENTE LIXIVIADOR, DE MANERA QUE UNA TIERRA RARA EN FASE IÓNICA EN EL MINERAL DE TIERRA RARA SE PUEDE LIXIVIAR EN UNA MODALIDAD DE INTERCAMBIO IÓNICO. ADEMÁS, A CAUSA DEL ACCIÓN REDUCTORA DE LOS IONES REDUCTORES, LOS IONES DE TIERRA RARA CON ALTA VALENCIA EN UNA FASE COLOIDAD Y UNA FASE MINERAL PUEDEN EXPERIMENTAR UNA REACCIÓN DE OXIDACIÓN - REDUCCIÓN, DE MANERA QUE SE FORMAN Y EXTRAEN POR LIXIVIACIÓN IONES DE BAJA VALENCIA, MEJORANDO ASÍ LA VELOCIDAD DE LIXIVIACIÓN DE UNA TIERRA RARA EN EL MINERAL DE TIERRA RARA CON ABSORCIÓN IÓNICA.</p><p> THE INVENTION GIVES TO KNOW A LIXIVIATING AGENT AND A IIXIVIATION METHOD FOR LIXIVING A RARE LAND IN A RARE EARTH MINERAL WITH IONIC ABSORPTION. THE LIXIVIATING AGENT IS A WATER SOLUTION THAT INCLUDES REDUCING IONS. A RARE EARTH WITH IONIC ABSORPTION IS LIXIVIATED BY A WATER SOLUTION THAT INCLUDES REDUCING IONS EAT A LIXIVIATING AGENT, SO THAT A LAND RARE IN IONIC PHASE IN THE RARE EARTH MINERAL CAN BE LIXIVED IN AN EXCHANGE MODE. IN ADDITION, BECAUSE OF REDUCING ACTION OF REDUCING IONS, LAND IONS RARE WITH HIGH VALENCIA IN A COLOITY PHASE AND A MINERAL PHASE CAN EXPERIENCE A REACTION OF OXIDATION - REDUCTION, SO THAT THEY ARE FORMED AND REMOVED BY LIX VALIDATION , IMPROVING THE SPEED OF LIXIVIATION OF A RARE LAND IN THE LAND MINERAL RARE WITH IONIC ABSORPTION. </p>
