20.500.12556/DiRROS-23010 Selective seperation of magnesium from Slovenian dolomites Although magnesium is one of the most abundant elements on Earth by weight, the demand for magnesium is constantly increasing due to its widespread use in a diverse range of industries such as metal alloys, electronics, batteries, agricultural and pharmaceutical compounds. For this reason, magnesium is categorised as a critical raw material by the European Union. Dolomite CaMg(CO3)2 is one of the most important mineral sources of magnesium, which in its pure form contains 13.18 % magnesium by weight. Various pyrometallurgical and hydrometallurgical processes have been developed and are used to extract magnesium from dolomite and other magnesium ores. In this study, samples of dolomite of different geological ages were collected in Slovenia and their elemental composition was analysed by microwave-assisted acid digestion and ICP-OES. Magnesium was then extracted by selective leaching and selective precipitation. Leaching was carried out with inorganic and organic acids. The separation of magnesium and calcium in a solution prepared by dissolving dolomite with acid was carried out by precipitation with hydroxide and oxalate. High extraction yields of magnesium and a significant separation between the two metals were achieved with both methods. magnesium dolomite extraction selective leaching selective precipitation magnezij dolomit ekstrakcija selektivno raztapljanje selektivno obarjanje true false true University of Belgrade, Technical Faculty Angleški jezik Slovenski jezik © authors, 2025 Neznano 2025-07-16 08:37:55 2025-07-16 08:46:01 2025-10-24 03:52:56 0000-00-00 00:00:00 2025 0 0 Str. 113-118 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-05-13 546.46:66.061.34:543.423 10.5937/IMPRC25113I 238466307 238457859 RAZ_Imperl_Jernej_2025.pdf RAZ_Imperl_Jernej_2025.pdf 1 C7B2EFA1FEE9F23C528D15FA9F717B9C 07a24594290ce7e5fe1085638227c1f7a9f1b8029128890047f7e14ead3bc494 74b1afa2-6210-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=33663 https://doi.org/10.5937/IMPRC25113I 0 8141e4e3-6210-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=33664 Zavod za gradbeništvo Slovenije 0 0 0
