稀土原矿浸矿新工艺,近日获得国家计委、科委和财政部联合颁发的国家“八五”科技攻关重大成果证书。该项成果是自1986年起由江西赣州有色冶金研究所立项攻关,并经过10年奋斗而终于取得成功的。该工艺不开挖、不运土,只要灌入化学溶液,整座山包中的稀土就会自动浸出。对山上植被不影响,无尾砂排放,而且稀土提取率可提高25％至30％,成本低,每吨约在千元以上。社会效益和经济效益显著,已被列入十大世界领先水平攻关成果。
Rare earth ore ore leaching new technology, recently won the State Planning Commission, Science and Technology Commission and the Ministry of Finance jointly issued by the State “85” major scientific and technological achievements certificate. This achievement has been tackled since 1986 by Jiangxi Ganzhou Institute of Nonferrous Metallurgy and finally achieved success after ten years of struggle. The process is not excavation, earth-moving, as long as the chemical solution is poured, the whole mountain package will automatically leaching rare earth. On the mountain vegetation does not affect, no tailings emissions, and rare earth extraction rate can be increased by 25% to 30%, low cost, about 1,000 yuan per ton. Significant social and economic benefits, has been included in the top ten world leading research achievements.
