加拿大《CMJ》今年第二期评介了1982年世界铜业生产情况,现将与冶炼有关的内容摘译如下。1982年加拿大铜价跌至三十年代以来的最低水平。由于价格低于生产成本,全加几乎所有的铜厂和不少矿山都停产几周乃至几月。去年加拿大矿铜产量为606202吨,比1981年低12%,今年产量可能只有52万吨。由于世界性铜消耗量下降,相应的生 Canada “CMJ” the second phase of this year reviewed the world’s copper production in 1982, the contents of the smelting are now extracted as follows. In 1982, the price of Canadian copper dropped to its lowest level since the 1930s. As the price is lower than the cost of production, nearly all copper mills and many mines in Canada and Canada have been shut down for several weeks and even months. Last year, Canadian mine copper output of 606,202 tons, 12% lower than in 1981, this year’s output may be only 520,000 tons. Due to the decline in world copper consumption, the corresponding students
