Study of Applicability of Existing Process for Deep Iron Ore in Lilou
To verify the applicability of the deep ore from Lilou Iron Mine in the current production process and optimize the ore beneficiation process in response to the changes in the properties of the raw ore,a study was conducted on the separation of deep ore under the existing process and the optimization of current production process indicators through the combined application of gravity-magnetic-flotation separa-tion and replacing the primary low-intensity magnetic separation with high-gradient magnetic separation.The final separation indicators achieved were a concentrate yield of 45.56%,an iron grade of 64.29%,and an iron recovery rate as high as 84.72%.The conclusion was drawn that the current production process of Lilou Iron Mine can meet the separation index requirements for deep ore,and replacing the primary low-in-tensity magnetic separation in the current process with high-gradient magnetic separation can optimize the separation effect.
