主 题：occurrence of RE phosphorites in Xinhua rare earths
摘 要：The RE and composition of trace elements analysis show that phosphorite-ores are rich in ∑ RE concentration generally in Xinhua, *** phosphorites were measured to gather LRE and HRE *** is higher than other *** phosphorite has enriched Y, La and Nd chemical *** are leading characteristics of concentrated La, LRE and Y, *** chondrite-normalized RE element patterns of the Xinhua dolomitic phosphorite distribute mode for rightwards type to one side of the ***/HRE 1, (La/Sm)N (Gd/Yb)N, and all indicate that LRE content is higher than *** test mode of chemical analysis of single mineral, chemistry phase analysis, scan electric analysis and micro-electronics probe analysis were *** chart of EDAX showed that there was representative element-Y(RE) in *** was no independent mineral of the *** is show that part of the few rare earth chemical element is adsorbed by the clay mineral, much for the type of quality isomorphic form exist in the apatite crystal structure of phosphorite inside.
