Such a waste often contains many impurities such as oil, paint, moisture, non-metallic fractions, oxides, Cu, Fe, etc. In this paper, two different methods for extracting magnesium from a highly contaminated waste are presented: the recycling of magnesium with flux and with the vacuum-distillation process. In addition, we present the process of pre-treating the contaminated magnesium waste that has proved to be a very important step in the recycling process for both economic and environmental reasons. The processing of post-consumer and contaminated magnesium scrap is described with a diagram, providing a sustainable and environmentally friendly procedure for the treatment of such wastesZ naraščanjem uporabe magnezijevih zlitin, posebno v avtomobilski industriji, se pričakujejo velike količine odpadkov na osnovi magnezijevih zlitin. Taki odpadki pogosto vsebujejo številne nečistoče, kot so olja, barve, vlaga, nekovinske frakcije, oksidi, Cu, Fe in drugo. V tem članku sta predstavljeni dve različni metodi za ekstrakcijo magnezija iz močno onesnaženih odpadkov: recikliranje magnezija s talilom in z vakuumsko destilacijo. Dodatno je prikazan še postopek predobdelave kontaminiranih magnezijevih odpadkov, ki se je izkazal za pomembnega pri recikliranju, tako iz ekonomskih kot tudi okoljevarstvenih razlogov. Obdelava iztrošenega in kontaminiranega odpadnega magnezija je opisana z diagramom, ki zagotavlja trajnosten in okolju prijazen postopek obdelave takih odpadkovTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
