economical ore
1.Ore deposits which have economical value mainly are depositional type and volcanegenic type produced in the permian period and tertiary period.
2.Abstract: As it was difficult to extract the ore in the delta zone at Ⅵ ore body of Jingtieshan Iron Mine,a rational extraction technology by ore cutting was applied so as to control the rock misplacement to ensure the extracted ore grade.As a result,good technical and economical benefits were achieved.

4.has been operating with 15%~20% Indian pellet instead of Australian ore. The output could increase by 7.6% and the coke ratio could decrease by 6.3% as compared with blast furnace operation with Australian ore. Good economical benefit has been achieved despite of high price of the Indian pellet.
