How would you separate two soluble solids physically, namely potassium chloride (KCL) and sodium chloride (NaCl)? Does it require dissolving both solids in water?

The simple thing it comes to my mind is to exploit their different solubility in water with temperature: if I remember correctly, NaCl should be more soluble than KCl at low temperatures (~0C).
