Abstract

In order to provide essential information for enterprises to exploit the iron ore of Yunnan province in China, properties of the ore were analyzed. Experiments of the best grinding fineness analysis and magnetic separation current were conducted. The result show that the ore is martite; when the grinding fineness content below 74um is 95%, and magnetic separation current is 10A (0.8T), iron concentrate with a grade of 65.40% and a recovery of 90.49% can be obtained. Sulfur and phosphorus content in the iron concentrate is 0.057% and 0.011%, respectively.
