摘 要：<正> The crystalline precipitate of rare earth carbonates has been produced by the ammonium bicar-bonate precipitation method in the recovery of RE from the ammonium sulfate leaching liquor of the weath-ered leach-deposited rare earth ore.Various influencing factors such as time,temperature and reagent con-centration have been studied.And chemical analysis,XRD,SEM,IR spectrography,TGA and DTA havebeen used to analyze and examine the crystalline RE carbonates.Good results were obtained.
