Study on Influence of Reduction Coal on Deep Reduction and Efficient Separation

Abstract:

The effect of four different kinds of coals on deep reduction and efficient separation of Lingyang iron ore from Linjiang was investigated in laboratory. And, tests for flowsheets of deep reduction and efficient separation with different coals as reductant were conducted. The result showed that coal had significant effect on the deep reduction and efficient separation. Iron powder was more superior in quality with an increase in the content of fixed carbon and reducing ash. And when washed coal with 12.02% of ash and 67.83% of fixed carbon was used as reduction agent in test, the iron powder with Fe grade of 88.09%, recovery of 88.32% and Metallization rate of 86.81% was obtained.
