Potash Ore Grades – Check the Units

May 20, 2015  Concentration Ratio is the Key When looking at different potash projects, particularly those involving underground mining, a key economic factor is the concentration ratio. This ratio represents the tonnes of potash ore needed to produce a tonne of final saleable product. Typically the final potash product has a grade of 60% K2O.
