Extraction of REE from a Mineral Rich in Iron Oxides

Extraction of REE from a Mineral Rich in Iron Oxides

Rare earths (REE) have attracted the attention of the world due to its importance for its application in advanced technologies, which has generated the optimization and development of new processes for its recovery from mine tailings, metallurgical slags and phosphorous gypsum. Globally, REE are obt...

Globally, REE are obtained mainly from carbonatites, alkaline igneous rocks, placers, laterites and clays. Monazite, apatite, and zircons are the main minerals that REE contains. This work presents the progress of the processing of an iron ore with REE contents. Flotation was performed using fatty acid and Fe and Si depressants. The tails were processed by magnetic separation. The non-magnetic material was leached using HCl and H2SO4 in order to investigate the influence of the type and concentration of acid. The results obtained indicated that HCl is the most efficient agent. Las tierras raras (REE) han atraído la atención del mundo debido a su importancia para su aplicación en tecnologías avanzadas, lo cual ha generado la optimización y desarrollo de nuevos procesos para su recuperación a partir de relaves de minas, escorias metalúrgicas y yeso fosforado. A nivel mundial las REE, se obtienen principalmente de carbonatitas, rocas ígneas alcalinas, placeres, lateritas y arcillas. La monacita, apatita y los zircones, son los principales minerales que contienen REE. En este trabajo se presentan los avances del procesamiento de un mineral de hierro con contenidos de REE. Se realizó flotación utilizando ácido graso y depresores de Fe y Si. Las colas fueron procesadas por separación magnética. El material no magnético fue lixiviado utilizando HCl y H2SO4 con la finalidad de investigar la influencia del tipo y concentración de ácido. Los resultados obtenidos indicaron que el HCl es el agente más eficiente.
