稀土矿中吸附性稀土总量的重量分析法

A Gravimetric Analysis Method about Determining Adsorbent Rare Earth Total Amount in RE Deposit

用７％ＮａＣｌ水溶液淋洗稀土矿，使吸附性稀土离子进入溶液，经氢氧化物沉淀分离后，用草酸盐重量法测定稀土矿中吸附性稀土总量，方法有较好的选择性。

Rare earth ore is showered with 2% NaCl solution,the adsorbent RE ions go into solution and are separated by hydroxide precipitation.The adsorbent RE total amount is determined by oxalic acid salt gravimetric analysis.The method has good selection,and can be applied to determine low content adsorbent RE total amount in the process of exploring and surreying RE deposit.
