Actually, this is a very simple metathesis reaction. Dissolving NaNO3 and KCl in hot water will produce a solution of Na+, K+, NO3-, and Cl- ions. Simply cooling this solution will cause the anion/cation combination with the lowest solubility to selectively precipitate out. Looking at some data for these salts:

KCl: 280g/L (0°C)
NaNO3: 730g/L (0°C)
KNO3: 130g/L (0°C)
NaCl: 360g/L (0°C)

Potassium nitrate has a relatively steep solubility vs temperature curve, and is the least soluble at 0°C, so it will crystallize very readily from a hot saturated solution that has been chilled to around the freezing point of pure water. Filtering out and collecting the precipitated KNO3 just leaves you with a solution of mostly Na+ and Cl- ions. The solubility of NaCl is quite high and doesn't change much with temperature, so it's possible to extract quite pure KNO3 directly from this reaction.
