中国稀土资源开采现状及发展趋势

这是一篇冶金工程领域的论文。以赣州地区某离子型稀土矿为研究对象,采用连续搅拌浸出和柱浸的方式,研究不同条件下矿样中稀土及杂质元素的浸出情况,为离子型稀土矿产资源的绿色高效开采提供参考。实验结果表明：连续搅拌浸出过程中稀土浸出率均在80%左右,二次浸出液中TREO/Al明显增大,TREO/Ca明显减小,TREO/Mg略微减小;柱浸实验中随着浸矿深度的增加,浸出液pH值逐步上升,TREO/Al增加至15.52,TREO/Ca降低至0.64。稀土浸出率均达到96%以上,但随着深度的增加轻稀土配分由49.43%上升到了53.28%,重稀土配分从35.91%逐步下降至32.18%。连续搅拌浸出和柱浸实验均表明随着矿样深度的增加,稀土浸出率无明显降低,低品位矿层稀土浸出仍然具有一定的可行性。
