    Hydrometallurgical Processing of Eudialyte Bearing

    ore is mined from the Lovozersky Mine to obtain a loparite concentrate for Nb, Ta, and REE recovery by the Soli kamsk magnesium works [17]. According to Zaitsev [18], the processing of eudialyte is just one option to increase further REE capacities. As a result, information about extraction processes is based on research and development

    Gold Leaching of Pyrite Concentrate

    The ore consisted of quartz, in which, above the 250 ft. level, the iron minerals were largely oxidized and some free gold was visible; below that level few traces of oxidation occurred, and pyrite constituted the principal mineralizer in the quartz, together with occasional pockets of galena and a few eccentric specks of covellite. The 20 stamp mill was equipped with plates for amalgamation

    important lithium ore mineral. A typical run of mine ore can contain 1 2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6 7% Li 2 O (75% 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.

    Hydrometallurgical Treatment of an Eudialyte Concentrate

    In this study a eudialyte concentrate from TANBREEZ ore was the raw material. TANBREEZ ore was exploited on southern Greenland, with the name TANBREEZ being an acronym of tantalum (Ta), niobium (Nb), REE and zirconium oxide (Z). After mining, the ore was sent for crushing and beneficiation, in which eudialyte concentrate was

    Selective recovery of niobium and tantalum from low grade

    Selective recovery of niobium and tantalum from low grade concentrates using a simple and fluoride free process. This could also be handled by mixing the purified Nb 2 O 5 183;nH 2 O with another Nb concentrate with a higher Nb/Ta ratio before the final production of ferroniobium. Furthermore, additional purification is expected during the
