半风化离子吸附型稀土矿可浸性试验研究

Experimental Research on the Leachability of a Semi-weathered Ion-adsorption Type Rare Earths Mineral

对某地半风化离子型稀土矿进行了可浸性试验研究。结果表明,该离子吸附型稀土矿可通过浸取富集,温度是影响浸出率的重要因素。并指出地浸工艺不能对其有效回收,建议此类稀土暂不进行开采利用。

The experimental research on leachability of a semi-weathered ion-adsorption type rare earms nunerat was performed. Test results showed that this ion-adsorption type rare earths mineral can be concentrated by leaching technology,and the temperature is an important factor influencing leaching rate. Because in-situ leaching does not effective recovery of rare earths, therefore authors suggested this kind of rare earths mineral resources is not necessarily immediately exploited at the present time.
