Separate Sand and Salt by Density. You can separate sand and salt much more quickly using the different densities of the two substances. The density of salt is 2.16 g/cm³ while the density of sand is 2.65 g/cm³. Put another way, if you filled a bucket with salt and another with sand, the one with sand would weigh more.
