How to Separate a Mixture of Salt From Sand | Reference.com

Salt melts at 1474 degrees Fahrenheit (801 degrees Celsius) while sand melts at 3110 degrees Fahrenheit (1710 degrees Celsius). In this regard, heating the mixture to temperatures above 1474 degrees Fahrenheit (801 degrees Celsius) will make the salt melt. Hence, decantation process can be used to separate the molten salt from the solid sand.
