Suppose you wish to separate a mixture of fine particles of gold and sand, neither of which is soluble in water. If you add liquid mercury to the mixture, the sand will float to the top of the mixture while the gold will dissolve. The sand can then be skimmed from the surface. You can recover the gold by heating the solution toevaporate the liquid
