　　The paper studied the extraction and separation of Fe3+ and Al3+, and efficient enrichment of RE3+ from oil shale ash as initial material.After most of Al3+and SiO2 were removed from the initial samples, the RE3+ content was about 100~200μg/ml, while the proportion of Fe3+ and Al3+ were still about 40~50%.Enrichment of trace of RE3+ from very high storage of shale oil residue would be regarded as a kind of beneficial supplement for available rare-earth ore.
