“…Metasomatic and albitofer type and a sub-community b The name of phosphorus iron type, which is a subset of phosphate type, exists in the region in which special attention can be paid to rare earth elements. [15,[19][20][21] In another study by Moghiseh et al (2014) in the tailings dam of the Choghart iron plant, in order to pre-concentrate the rare earth elements, the reagent sample was removed, and XRF analysis was performed on the sample with cerium, lanthanum, neodymium with 120, 98 and 350 ppm of light rare elements and yttrium, gadolinium and erbium with 630, 110 and 23 ppm of heavy rare elements showed the highest values, respectively. According to the results of minerals identified in XRD and the properties of rare earth minerals, a series of processing operations were performed on it, which have the grade of cerium, lanthanum, neodymium, and yttrium, gadolinium and erbium, respectively, equal to 4.335, 4.278, 1010.…”
