摘要
研究了风化壳淋积型稀土矿矿石性质及稀土在各粒级上的含量。采用热重分析、EDTA容量法、紫外分光光度法、原子吸收分光光度法、甲醛容量法等测试手段,对矿石的多水性、吸附稀土离子的稳定性、原矿的缓冲性、吸附离子的可交换性这四大物理化学性质进行了验证,对稀土在各粒级上的含量进行了测定,为进一步合理利用该矿石资源提供理论指导。
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.
