| Abstract: | Problems exposed during ultralean magnetite treatment by primary technological process of Ma Steel Washan concentration plant were described briefly, then modification scheme research and demonstration were done through laboratory test, modification scheme and effect after modification were introduced mainly. Practice improved, technological process after modification had significant quality improvement and impurity reduction function and high stability, could steady the iron concentrate grade of Washan concentration plant above 64%. |
