Coarse flotation technologies are now emerging as real options for miners They will have a significant impact on energy use and grinding time thereby reducing costs and power consumption and improving productivity In this post CEEC shares some highlights
Therefore grinding ore down to 400μm for coarse particle flotation will use much less energy and equipment than grinding down to 150μm for conventional flotation as an example “Another benefit is that a significant percentage of the runofmine ore can be separated and rejected while it is still very coarse often between 400600μm
