| Abstract: | The ore properties of the weathered crust elution-deposited rare earth ore and rare earth contents in various grain-size are studied.The TGA,EDTA volumetric method,UV spectrophotometry,atomic absorption spectrophotometry and formaldehyde volumetric method are chosen to verify the four physical and chemical properties of the weathered crust elution-deposited rare earth ore as follows,the ore with many kinds of water,the stability of absorbing rare earth ions,the buffer of raw ore and the exchangeability of ions adsorbed.And with the measurement of rare earth contents in various grain-size,a theoretic guidance in the rational utilization of this ore resource is provided. |
