根据国际镁协会的资料,从1979年起,镁的生产量超过了镁的消费量。例如,1979年,镁的生产量是22.6万吨;消费量是22.45万吨,1980年镁的生产量是23.6万吨,消费量是21.9万吨;1981年镁的生产量是20.85万吨,消费量是20.3万吨;1982年镁的生产量是17.5万吨,消费量是20.2～20.5万吨。1982年对镁的需求量停留在1981年的水平上。但是,由于过分增加库存量,使得镁的生产量减少了。尽管美国仍然是镁的最大生产国,但在世界镁生产中,美国所占的比例已下降到44%。挪威镁的生产占世界的第三位,达14%。 According to the International Association of Magnesium, since 1979, magnesium production has exceeded magnesium consumption. For example, in 1979, the production of magnesium was 226,000 tons; the consumption was 224,500 tons; in 1980, the production of magnesium was 236,000 tons and the consumption was 219,000 tons; in 1981, the production of magnesium was 208,500 tons, The consumption was 203,000 tons; in 1982, the production of magnesium was 175,000 tons and the consumption was 20.2-20.5 million tons. The demand for magnesium in 1982 remained at the level of 1981. However, the production of magnesium is reduced due to an excessive increase in the stock. Although the United States remains the largest producer of magnesium, the share of the United States in the world magnesium production has dropped to 44%. Norway’s magnesium production accounts for the third place in the world, reaching 14%.
