Caption: Separating salt from rock salt. Rock salt being separated from its impurities. Here, crushed rock salt is added to warm water to dissolve the salt. The solution is then filtered to remove any insoluble impurities and heated gently to evaporate off the water. This will leave the pure salt behind.
