一、我国铜供需情况分析 经过新一轮资源评价,我国铜矿资源现有储量1662万吨;储量基础为2732万吨;仅居世界第8位;人均占有储量更少,仅为世界人均储量的五分之一,我国是一个铜矿资源缺乏的国家。 到2000年底,我国铜矿山形成年采选49.89万吨金属的生产能力;仅为国内粗铜冶炼能力的47.5％,矿山生产远不能满足冶炼生产的需要,目前国内一半以上的铜产量是利用进口原料生产的。 我国正在生产的铜矿山大部分是20世纪40～50年代建设的,
I. Analysis of copper supply and demand in China After a new round of resource assessment, China’s current reserve of copper resources is 16.62 million tons; the reserve base is 27.32 million tons; it ranks only in the world’s eighth place; per capita possession is less, only world per capita reserves One-fifth of our country is a country lacking in copper resources. By the end of 2000, China’s copper mines will have an annual production capacity of 498,900 tons of metal; only 47.5% of domestic crude copper smelting capacity, and mine production is far from meeting the needs of smelting production. At present, more than half of domestic copper production is imported. Raw material production. Most of the copper mines that China is producing are built in the 40s and 50s of the 20th century.
