摘　　要：报道从重稀土型低品位稀土矿中制取晶型碳酸稀土的工业实验情况。在渗浸过程中加入一种抑制铝的添加剂，使浸出液不用净化除铝，即可制得高质量的晶型碳酸稀土。This paper reports on the full scale tests of production of crystalline rare earth carbonates from low grade heavy rare earth ores.The results showed that adding an inhibitor of aluminium during the percolation leaching permits the crystalline carbonates to be manufactured from the leach liquor without the purification steps for removing aluminium.

关 键 词：低品位 稀土矿 碳酸稀土 晶型 重稀土冶炼
