过去10年，中国镁产量稳步增长。大多数金属是通过皮金法生产的。该过程在熔炉中和真空下使用称为蒸馏器的水平钢管。在蒸馏器中，细磨的煅烧白云石和硅铁的混合物形成团块，反应形成镁蒸气，镁蒸气被冷凝，然后重熔成锭。皮江法长期以来被认为是不经济且过时的。中国利用优质原材料、地理位置、大量熟练劳动力供应和较低资本成本的优势，通过这种工艺生产镁。中国镁的销售价格是全球最低的，按磅计算，其价格低于铝。
Magnesium production in China has been growing steadily over the past 10 years. Most of the metal has been produced by the Pidgeon process. This process uses horizontal steel tubes called retorts, in furnaces and under vacuum. In the retorts mixtures of finely ground calcined dolomite and ferrosilicon formed into briquettes react to form magnesium vapors which are condensed and later remelted into ingots. The Pidgeon process was long thought to be uneconomic and obsolete. The Chinese have used the advantages of excellent raw material, location, large skilled labor supply, and low capital costs to produce magnesium by this process. The Chinese magnesium is being sold at the lowest prices in the world and lower than aluminum on a pound for pound basis.
