I am interested in model rocketry, and need to produce small quantities of pottasium nitrate. For this process I need ammonium nitrate, but I only have calcium ammonium nitrate. Is there a simple process for removing the calcium?

4$\begingroup$ If you add ammonium sulfate then the calcium will precipitate out and not waste as much of your nitrate content. $\endgroup$– A.K.Aug 4, 2018 at 18:53

Soak it in water and decant off the aqueous solution freeze and the crystals should form its just calcium carbonate and ammonium nitrate dont recommend using heat.
