Abstract

DICHO PROCESO COMPRENDE LA REDUCCION DEL CONTENIDO DEL HIERRO DEL ACIDO FOSFORICO POR VIA HUMEDA, LA REDUCCION DE LA VALENCIA DE CUALQUIER HIERRO FERRICO RESTANTE EN EL ACIDO FOSFORICO POR VIA HUMEDA A HIERRO FERROSO, Y LUEGO LA EXTRACCION DE LOS COMPUESTOS DE URANIO A PARTIR DEL ACIDO FOSFORICO POR VIA HUMEDA. EL PROCESO PUEDE INCLUIR LA SEPARACION DEL ACIDO FOSFORICO POR VIA HUMEDA DE UNA CORRIENTE LATERAL QUE TIENE UNA MAYOR CONCENTRACION DE LOS COMPUESTOS DE URANIO QUE EL ACIDO FOSFORICO POR VIA HUMEDA AL PASAR EL ACIDO FOSFORICO POR VIA HUMEDA A TRAVES DE UNA MEMBRANA DE FILTRO PARA PRODUCIR UN PERMEATO DE ACIDO FOSFORICO POR VIA HUMEDA LIMPIO Y UN RETENTATO COMO LA CORRIENTE LATERAL, EL RETENTATO QUE COMPRENDE UNA MAYOR CONCENTRACION DE LOS COMPUESTOS DE URANIO QUE LA CONCENTRACION DE URANIO EN EL PERMEATO
