摘　　要：A new technique of magnesia electrolysis from bischofite in Qinghai salt lakes was investigated experimentally. Magnesia was prepared by ammonia processing. On an electrolysis cell of about 100 A capacity at 700degreesC, magnesium metal was obtained with a current efficiency of 90.23% and a specific energy consumption of 11.5 kW(.)h. The new technique has the advantages of energy saving, high current efficiency and environmental amity.A new technique of magnesia electrolysis from bischofite in Qinghai salt lakes was investigated experimentally.
