美国历年来钼的产量、消耗量以及出口量均占世界第一位。然而,在八十年代,这三方面均处于下降趋势。美国1985年钼产量为4.7万吨,是历史最高年产量1980年6.9万吨的68%,占世界当年产量的58%;消费量1965年为1.7万吨,是历史最高消费量1979年3.2万吨的53%,占世界当年消费量的22%;1985年其出口钼精矿量为5.08万吨(合111.9百万磅),是历史最高年1973年出口量6.13万吨(合135.1百万磅)的83%。 Over the years, the United States molybdenum production, consumption and exports accounted for the first place in the world. However, in the eighties, all three aspects were in a downward trend. The U.S. production of molybdenum was 47,000 tons in 1985, the highest annual output in 1980, 68% of the 69,000 tons in 1980, accounting for 58% of the world’s total output. The consumption was 17,000 tons in 1965, the highest historical consumption in 1979 32,000 Accounting for 53% of the total tonnage, accounting for 22% of the world’s total consumption in that year. In 1985, its export volume of molybdenum concentrate was 50,800 tons (111.9 million pounds), the highest in history in 1973, with 61,300 tons (135.1 million tons) Pounds) of 83%.
