摘要
对西南某地低品位稀土复合矿采用焙烧-酸浸工艺,稀土的浸出率大于81%,Nb的浸出率大于88%,Ga的浸出率可达99.08%,较好地实现了该稀土复合矿的综合利用。
A low grade complex rare earth ore on the southwest area was processed by roasting and acid leaching process. The result shows that the leaching rate of rare earth is above 81%, the leaching rate of Nb is above 88% and the leaching rate of Ga reaches 99.08%, which achieves comprehensive utilization to the rare earth ore.
