Abstract

Un proceso y planta para la transformacion de residuos peligrosos con contenido de cromo seis como contaminante en residuos no peligrosos que pueden ser almacenados sin cuidados especiales y van a ser degradados en el medio ambiente sin límites de tiempo. El proceso básicamente consiste en una molienda, extraccion del cromo seis en fase líquida y en condiciones controladas de agitacion, tiempo y temperatura, para posteriormente proceder mediante reduccion, transformar el cromo seis en cromo tres y su posterior precipitacion como tritoxido de cromo , por gasificacion. El solido resultante del proceso de transformacion, puede ser utilizado como materia prima para la construccion de ladrillos refractarios o eventualmente para la fabricacion de tabiques utilizados en la construccion mediante un proceso que no se incluye en la presente descripcion.
