Potash Ore Grades – Check the Units
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.

Potash Mining | SpringerLink
Abstract. The mining of large underground potash deposits presents an unusual challenge because the quantity of ore to be mined is very large, the value of the ore is relatively low, there is extreme competition, and most dominately, at the depth of many potash mines there are severe stress and creep (plastic flow) problems.
