Scale-up test and an annual1200-ton-magnesium demonstration-level test was conducted to confirm the rationality, reliability, and advancement of the equipment, system and process design. It is indicated that the new technology solved a series of problems of traditional silicothermic process including adhesion and glaze, short life of retort, low efficiency, high impurity of crystallized magnesium, large heat losses, and poor working environment,making a great technological breakthrough in this field. Representatively, the new well-designed ceramic-lined steel retort serves 2~3 times in life than the normal retorts. The magnesium yield per retort is improved 4~5 times, with purity of >99.8%. The energy consumption in reduction stage is reduced by more than 20%. The mechanical production is fully realized and operating environment is significantly improved.展开更多

The produced water was sent for analysis. The different samples were analyzed for carbon content, and results showed that the TOC was 2010 mg per liter of retorted water. Phenol and arsenic contents were measured and found to be 64 mg and 0.18 mg per liter respectively. Phosphate and sulfate were also determined and found to be 35.7 and 5022 mg per liter. On the other hand, ammonium was also found to be 2831 mg per liter. Several elements were traced and reported in the present work, in which arsenic, chrome and nickel are the most important, and the retorted water was found to contain 0.18, 0.7 and 0.5 mg per liter.展开更多
