前言罗辛铀厂位于纳米比亚的斯瓦科普蒙德(Swakopmund)城东北70公里。处于沙漠地带,平均海拔576米,气候干燥,风沙多,降雨量少,每年平均仅30毫米,而温度和湿度变化范围相当大,分别为5—40℃和5—80%。勘探结果表明,该地区有个很大的低品位铀矿床,适于露天开采和用较简单的方法提取铀(图1)。为了 Preface Rohing uranium is located 70 km northeast of Swakopmund in Namibia. In the desert, the average elevation of 576 meters, the climate is dry, windy, less rainfall, an average of only 30 millimeters per year, while the temperature and humidity range is quite large, were 5-40 ℃ and 5-80%. The exploration results show that there is a large low-grade uranium deposit in the area suitable for open-pit mining and extraction of uranium by a simpler method (Figure 1). in order to
