1981年虽然经济不景气,但湿法冶金的研究工作和工业活动仍十分活跃。金属价格的跌落对1982年的湿法冶金活动将会有重大的影响。溶液采铀和贵金属回收是1981年湿法冶金所强调的两个课题。看来引起注意的另一课题是复合矿的湿法冶金处理,特别是以氯化物为介质进行处理。 这一年,先后召开了与湿法冶金研究课题有关的若干次重要会议。2月22—24日,美国 Despite the economic downturn in 1981, the research and industrial activities of hydrometallurgy are still very active. The drop in metal prices will have a significant impact on hydrometallurgical activities in 1982. Uranium solution recovery and precious metal recovery are the two topics highlighted by the 1981 hydrometallurgy project. Another issue that seems to attract attention is the hydrometallurgical treatment of composite mines, especially with chloride as a medium. This year, has held a number of major conferences related to hydrometallurgy research topics. February 22-24, United States
