“…This mineral has been found in all the discussed massifs, although it occurs in them in different proportions [78][79][80][81][82][83][84][85]. In the Lovozero massif, it is relatively common, occurs as an accessory mineral, and is a rock-forming mineral in some pegmatites.…”

This manuscript deals with the analysis of significant rare earth elements (REE) minerals such as eudialyte, lorenzenite, loparite, perovskite, titanite, apatite, and carbonates. These minerals are found in the rocks of the Khibiny, Lovozero, Afrikanda, and Kovdor massifs (the Paleozoic hotspot activity in the Kola-Karelian Alkaline Province is estimated at about 100,000 km2). Performed microscopic analyses that demonstrated their structure and optical features (dimming, interference colors, relief). Single-crystal analysis using XRD methods, SEM-EDS, and spectroscopic (FTIR) studies allowed the characteristics of described minerals: Lorenzenite in Lovozero probably crystalized after loparite have small additions of Nb, La, Ce, Pr, and Nd. Loparite and perovskite have the addition of Ce, Nb, and Ta. The same dopants have titanite probably crystalized after perovskite. Calcite in these massifs had the addition of Ce and Sr, the same as in fluorapatite, which was found in these rocks too. All of the analyzed minerals are REE-bearing and can be considered as deposits.

“…The method of chlorination of loparite concentrate is used to obtain REE (JSC SMP 2021). Research is underway to improve this method and increase the yield of the final product (Skiba et al 2003; Lebedev and Rudenko 2005; Belova 2017). However, new techniques for the loparite processing are being developed.…”

There are rich deposits of rare earth elements (REE) in the Murmansk region, Russia (approximately 14 194 kt of REE 2 O 3 ). At the moment only one of REE deposits are being extracted and processed, the Lovozero Loparite deposit. The main purpose of this article is to estimate the expected value of existing REE resources in the Murmansk region and to make an overview on actual technologies for the extraction and processing of REE from ore minerals. Based on these data, the authors propose a direction for the development of REE industry in the region, namely extraction of REE from minerals already mined (apatite of the Khibiny deposits and baddeleyite of the Kovdor deposit); optimisation or development of mineral processing technologies of eudialyte (the Lovozero Eudialyte deposit) and perovskite (the Afrikanda deposit); carrying out exploration works at the Keivy Zr-REE ore occurrences and developing processing and technologies for these ores.
