一、前言近年来世界核电站不断增多,铀的需要量急剧增加。据美国《铀矿资源》报导:1970年铀的需要量为1.09万吨U_3O_8,又据经济合作与开发组织报导:1980年铀需要量为2.8—3.2万吨U_3O_8,十年增长了两倍左右。在这种形势下,高品位铀矿石因大量开采而日趋减少,处理低品位铀矿又使生产费用增高。1970年资本主义国家铀矿资源的 I. Introduction In recent years, the world’s nuclear power plants have been increasing and their uranium needs have risen sharply. According to the U.S. Journal of Uranium Resources, the demand for uranium in 1970 was 10,900 tons U_3O_8. According to the Organization for Economic Co-operation and Development, the demand for uranium in 1980 was 2.8-3.2 million tons U_3O_8, a ten-year increase of about two times . Under such circumstances, the high-grade uranium ore is declining due to the large-scale mining and the production cost is also increased by the treatment of low-grade uranium ore. 1970 capitalist uranium resources
