It worth remembering that 27Kt salts does not equal 27Kt SOP.
At steady state they need 2.27Mtpa of salts and the addition of 42Ktpa MOP.
They have 1/84 of salts required for steady production. Definitely a demo plant.
They will produce roughly 2.9Kt of SOP.
They are along way from producing 50Ktpa.
