含铀原料的综合利用 副产钒 五十年代初,美国就已开始在铀的工业生产中副产钒。目前,许多工厂仍在继续生产钒。此外,一些国家的铀工厂已经改变工艺流程,以便副产钒。 目前,美国格兰茨铀厂(属联合核子霍姆斯特克合股公司)是一座拥有提钒车间的最大铀工厂(图1)。矿石在压热釜和帕丘卡槽中两段碳酸盐浸出、在三段转鼓过滤机中过滤分离含铀溶液、含铀溶液在特殊的增稠器中澄清后,用氢氧化钠从澄清溶液中沉淀铀。制得的铀化学浓缩物含75—77％U_3O_8、5—6％V_2O_5和2—2.5％CO_2。为了除去钒和碳酸根,沉
Comprehensive Utilization of Uranium-Containing Raw Materials by-Production Vanadium In the early 1950s, the United States began to produce by-product vanadium in industrial production of uranium. At present, many factories are still continuing to produce vanadium. In addition, uranium mills in some countries have changed their processes in order to make vanadium by-products. Currently, the US Grant Land Uranium Plant (a joint stock of Nuclear Holmström) is the largest uranium plant with a vanadium extraction plant (Figure 1). Ore in the autoclave and Pachuca tank carbonate leaching two sections, in the three section drum filter filter containing uranium solution, containing uranium solution clarified in a special thickener, with sodium hydroxide from Clarified solution precipitated uranium. The prepared uranium chemical concentrate contains 75-77% U_3O_8, 5-6% V_2O_5 and 2-2.5% CO_2. In order to remove vanadium and carbonate, Shen
