- use magnet to separate iron nails and keep them in separate box {magnetic separation} by seaving separate stones from sand and salt.Keep stones separately now we have left with sand and salt.Add water to sand and salt. Salt will dissolve in water. Then allow filteration ( us a muslin cloth) or sedimentation decentation.sand will be collected as residue on the cloth let it dry and then store it. salty water will be collected as filtration. evaporate water from salt by heating.
