本文对草酸—碳铵混合物(H_2C_2O_4·2H_2O—NH_4HCO_3)作沉淀剂处理离子型稀土矿水的工艺条件作了系统的试验,找出了提取稀土的最佳工艺条件,很有希望降低提取成本和提高效益。
In this paper, we systematically tested the technological conditions for the treatment of ionic rare earth mine water with oxalic acid-ammonium bicarbonate mixture (H 2 C 2 O 4 · 2H 2 O-NH 4 HCO 3) as precipitant, and found out the optimum technological conditions for rare earth extraction. It is very promising to reduce the extraction cost and Improve efficiency.
