【《瑞士原子能协会通报》1991年第1期第7页报道】据巴西国家铀生产和加工公司Uranio do Bnasil的报告,巴西铀矿资源高达约30万吨U_3O_8,其中约20万吨为已登记的储量,其余为估计的补充储量。最重要的铀矿床位于巴西东北部的Itataia,东部的Lagoa Real和东南部的Pocos de Caldas。迄今只开采了Pocos de Caldas的矿床,开采量为500吨铀/年。因为在Pocos de Caldas矿山开采铀的成本较高而且铀储量有限,Uranio de Brasil公司计划将铀的开采移至较
[Report of the Swiss Atomic Energy Society, 1st Issue, 1991, p.7] According to Uranio do Bnasil, Brazil’s national uranium production and processing company, Brazil’s uranium resources are as high as 300,000 tons U_3O_8, of which about 200,000 tons are registered. The reserves are the rest of the estimated supplementary reserves. The most important uranium deposits are located in Itataia in northeast Brazil, Lagoa Real in the east and Pocos de Caldas in the southeast. So far, only the Pocos de Caldas deposit has been mined, with a mining volume of 500 tons of uranium/year. Uranio de Brasil plans to move uranium mining to higher levels because of the higher cost of uranium mining in the Pocos de Caldas mine and the limited uranium reserves
