Abstract
High-end Mg alloys need high-purity and stable primary Mg with affordable price. However, current commercial primary Mg either has poor quality (e.g. Mg9990) or is of high price. After 8 years of research and development, we developed a technology that is capable of large-scale production of high quality pure magnesium at a low cost. In addition, we had built the first thousand-ton Mg9995A demonstration line in China successfully based on the existing horizontal reduction retort. During a one-month trial period, the compliance rate of the produced magnesium is over 90% without reducing total production or increasing operational complexity. The application and promotion of this technology are expected to improve the quality of the whole industry chain and provide a fundamental guarantee for the healthy development of magnesium industry.
