| Abstract Scope |
The recently funded EIT EU Magnesium project seeks to contribute to the first domestic Magnesium production in Europe. At present, Europe fully depends on Chinese imports. Last year there was an enormous Mg supply disruption because of an electricity shortage in China. The European aluminium industry was dramatically affected by the Mg supply disruption and corresponding price spike. The magnesium price reached a record of US $ 12.000 /mt up from US $ 2.000 /mt earlier in the year. In the Mures County in North-central Romania, 1.94 million tonnes of chromium ore process residues (COPR) are available as Mg, but also as additional Cr and CaCl2 and NaOH resource. Mures SRL will construct the plant on its 84-ha property to produce mainly Mg metal and other by-products. Hydrometallurgical ecological processing will be used to recover not only Mg but the hazardous Cr6+ which will be recovered as Cr2O3 rendering this process environmentally friendly. In addition, the process will incorporate a mixed salt electrolytic unit to convert MgCl2 to Mg metal which is a low carbon footprint route in comparison to the conventional Pidgeon process employed mainly in China. With a ca. 19,000 tpy of Mg metal capacity in phase 1 of operation (2026 – 2034), Mures will contribute13.5% of the EU Mg demand during the first 9 years. In phase 2 (beyond 2034), micronized dolomite will be used as the feed material and the capacity will be increased to 25,000 tpy Mg equivalent to 15% of EU demand. |
