A New Hydrometallurgical Process Combined with an Electrolytic Process for Magnesium Primary Production from Serpentine: Joel Fournier1; 1Alliance Magnesium
     The primary production process developed by Alliance Magnesium Inc. is a hydrometallurgical process combined with an electrolytic process. It constitutes an improvement over the former Noranda Magnola Process and uses a combination of best in class technology to produce a high-quality magnesium for use in many applications, including the most demanding, namely the automotive market. It also introduces a radical breakthrough technological change by the production of some valuable by-products.The process allows processing and extracting magnesium from tailing, such as asbestos mine tailing, obtained after processing of magnesium-bearing ores and including a multi steps continuous line through the preparation and classification of the ores, the magnetic separation, a strong acid leaching, a liquid/solid separation ans washing, a resin captation ans hydrolysis recovery, dehydration and electrolysis.

Thermodynamics on the Recycling Process of Mg Alloys Containing Ca, Sr and RE: In-Ho Jung1; Jeong-Min Cheon1; Minsuk Kang1; 1Seoul National University
    The application of Mg alloys containing Ca, Sr and RE is expanding recently due to its good high temperature mechanical properties, formability and corrosion resistance. For the sustainable usage of these alloys, it is highly necessary to develop the proper recycling process of the Mg alloys. In the common melting recycling process of Mg alloys, molten salt of Na,K,Ca//Cl,F system is used to as refining flux. In the present study, the thermodynamic database for the Na,K,Mg,Ca,Sr,RE//Cl,F salt system was constructed and applied to the chemical equilibrium calculations between molten salts and liquid Mg alloys to investigate the refining recycling process of Mg alloys.
