摘要
Platinum Group Elements (PGE) has been received increasing attention due to their extensive existence in various geological environments. PGE geochemical analysis shows that with increasing of lateritization, the concentration degree of the PGE is higher. And PGEs have different values at different positions even in the same regolith, indicating that PGEs migrated, enriched and differentiated in the regoliths in company with the process of lateritization. The study found that Fe2+ is of great importance to the reduction of PGE complex and that the sorption of Fe3+ oxide to PGEs also has great impact on the redistribution and enrichment of PGEs. Different geochemical features of six elements in PGEs result in the differentiation in red regoliths, and Rh shows highly consistent with the overall performance of PGEs during the lateralization.
