摘要
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。
With oxatatc-ammonium bicarbonate mixture as the precipitant this article studied the conditions in which the chemically-precipitated rare earth from mineral water was treated. Therefore, the optimum conditions were suggested in extracting rare earth to hopefully reduce the cost and to promote the efficiency.
