铀矿石加压水浸,又称加压自氧化浸出,是在加温加压下利用空气中氧或纯氧直接氧化硫化矿中的硫或元素硫产生硫酸进而浸出铀的过程。它具有节省试剂、强化浸出过程,和因浸出液中杂质少而便于回收铀等优点。1953年起,加拿大、澳大利亚等国开展了这方面的研究工作。到五十年代末和六十年代,美、英、西德等国也相继发表了各种硫化物加压氧化的研究报告。在我国第一届冶 Pressurized uranium ore flooding, also known as pressurized autoxidation leaching, is the use of oxygen in the air or oxygen at the direct oxidation of sulfur in sulfide ore or elemental sulfur to produce sulfuric acid leaching uranium process. It has the advantages of saving reagents, enhancing the leaching process, and facilitating recovery of uranium due to less impurities in the leachate. Since 1953, Canada, Australia and other countries carried out research in this area. By the late 1950s and the 1960s, the United States, Britain, West Germany and other countries also published various studies on the pressurized oxidation of sulphides. The first rule in our country
