Hello evrybody

I wanna to know after performing davis tube test for a iron ore sample how can we predict the number of roughing and cleaning stage for plant design? Is this completely on previous experience?

Thanks for your guidance

The Davis tube only gives you a rough idea of whether the material is separable by magnetic methods.  It cant/should be used to define a flowsheet.  You need a more detailed laboratory test using wet drum magnetic separators, electrostatic separators and likely gravity.    It starts with ore characterization and then defining the test program, how much weakly magnetic material is there, how much strongly magnetic material, does gravity work for a primary separation.
