1986年4月上旬,我们有机会参观了法国的低品位小铀矿和高品位大铀矿。经过座谈讨论,认为法国的低品位小铀矿的开发,抓住了简易、经济两个关键,值得参考。 贝托勒纳(Bertholene)矿区位于法国南部,西距罗德兹(Rodez)镇20公里。60年代发现铀矿,由铀和放射性金属矿产公司组织领导。1982年建成露天矿,生产的矿石送坎特省的圣·皮埃尔矿区水冶厂处理,经济效益低。1983年该矿区转卖给法国多塔尔(Total)矿产公司经营管理,该公司制定了干式破矿、大池渗滤、清液吸附的工艺流程,就地建成简易水冶厂。生产的饱和铀树脂,连同吸附容器,一起送儒雅克(Jouac)中央水冶厂淋洗、沉淀,生产黄饼。
In early April 1986, we had the opportunity to visit French low grade uranium mines and high grade uranium mines. After discussion and discussion, that France’s low-grade small uranium development, seize the simple, economical two key, it is worth considering. The Bertholene mine is located in southern France, 20 km west of Rodez. The discovery of uranium deposits in the 1960s was led by uranium and the organization of radioactive metal mineral companies. In 1982, an open pit mine was built and the ore produced was sent to San Pierre Mining and Metallurgical Plant in Kante province for low economic benefit. The mine was resold to Total Minerals in France in 1983 for management and operation. The company has established a process for dry-type rock breaking, large-pool percolation and supernatant adsorption, and built a simple hydro-metallurgical plant on site. The production of saturated uranium resin, together with the adsorption vessel, is sent to the Jouac Central Waterworks for rinsing and sedimentation to produce yellow cakes.
