I want to extract Ammonium Nitrate and KNO3 from fertilizer that is called Potassium Ammonium Nitrate + MgO. It contains some MgO, ammonium nitrate
and KNO3 with some sand mixed in. What would be the best way to extract both chemicals? I want to make ammonium compounds from that and potassium
compounds from KNO3. Though maybe its Calcium Ammonium Nitrate, but now I am not sure.
