Study on Influencing Factors of In-situ Leaching of Ionic Rare Earth Ore AITranslate
Abstract AITranslate
Simulated in-situ leaching tests of ionic rare earth ore were carried out,and the influences of type,concentration,pH value and flow rate of the leaching agent,solid-liquid ratio and temperature on RE and Al leaching rate were investigated.The results show that the average leaching rates of RE and Al are 94.56%and 45.10%,respectively,using ammonium sulfate as the leaching agent with concentration of 2%,pH va-lue of 4.50 and flow rate of 10 mL/min,and under the leaching conditions of solid-liquid ratio of 1∶0.66 and room temperature.The results of extended leaching test show that the leaching rate of RE and Al are 94.58%and 45.96%,respectively,realizing the high-efficiency leaching of RE,while the impurity Al is less leached.
