Object: Three kinds of traits of haematitum including the crude and processed drugs are analyzed and compared in this paper. Methods: By SEM/EDS method, experiments are conducted on phase, morphology, grain size and surface trace. Results: The comparison table of trace elements and the scanning electron micrographs of the six samples are achieved in this paper. Conclusion: It shows that there are different among the haematite of three different properties whether the crude or processed drugs. It needs further study whether all these Haematitum can be used as one mineral medicine.
