摘　　要：从环境和能耗角度评价国内外的几种主要炼镁方法。通过对比评价得出:以菱镁矿石氯化生产的氯化镁为原料的熔盐电解法具有最小的能量消耗,其次是内加热的硅热法炼镁技术;如果不考虑还原剂的生产能量消耗,内加热的硅热法炼镁能量消耗最少;金属热还原法炼镁对环境影响小,具有极好的发展前景。文章最后提出了我国镁冶金技术发展的建议。In present paper the different magnesium reduction methods were reviewed in terms of their environmental impact and energy consumption. The conclusion reveals that the electrolysis process with MgCl2 through magnesia chlorination needs minimum energy consumption. And the production of magnesium through thermochemical reduction with the electrical resister heater situated in reduction furnace has lower energy consumption and pollution, so it has advantages over other methods and can be well developed. Some propositions on the development route of magnesium metallurgy in China were made in this paper.
