Well, I have to get each of these by themselves, Pottasium Nitrate is 100% soluble in water at 60 degrees celcius, so if the sand was alone in that it would work, but salt is only 38% soluble in water so filtering wouldnt work...

Could someone tell me what would be the best way to separate these 3 solids. Potassium Nitrate, Sodium Chloride (Salt), and sand, all of which are in water. Any insight would be helpful thanks.
