根据美国矿山局的估算,1975～2000年期间美国铜消费量的年增长率如以3.5％计,到2000年铜的需要量将达到510万吨。世界其他国家的总需要量将为1600～2700万吨,平均2100万吨。 2000年美国有关工业部门铜的需要量是:电气工业—1600～480万吨(平均360万吨);建筑业-40～80万吨(估计60万吨);机器制造业—35～55万吨(平均40万吨),交通运输业—估计为20万吨;军火工业—估计为10万吨。在铜矿找矿方面,预计将采用新的地球化学采样技术和工艺,利用红外线遥感照片发现异常。同时应加强成矿过程的研究,以便在最有潜在希望的地区安排勘探工作。
According to the estimation of the US Bureau of Mines, the annual growth rate of copper consumption in the United States during the period 1975 to 2000 was 3.5%. By the year 2000, the copper demand will reach 5.1 million tons. The total demand of the rest of the world will be 1600-27 million tons, an average of 21 million tons. The demand for copper in the industrial sector in the United States in 2000 is as follows: -1600-48 million tons (3.6 million tons on average) in the electrical industry; -40-80,000 tons (600,000 tons) in the construction industry; 355,000-550,000 in the machinery manufacturing industry Ton (average 400,000 tons), transportation - estimated at 200,000 tons; arms industry - estimated at 100,000 tons. In prospecting for copper deposits, it is estimated that new geochemical sampling techniques and processes are expected to be used to detect anomalies using infrared remote sensing photographs. At the same time, research on the process of mineralization should be strengthened in order to arrange exploration work in the most promising areas.
