As a chemist, you have numerous methods at your disposal to separate sand and salt. However, the simplest approach involves combining two basic separation techniques we've previously discussed: filtration and evaporation.Through filtration, you can isolate the sand from the saltwater solution.

The term soil separates is used to describe the mineral particles (sand, silt, clay) that make up the fine earth fraction. Sand – the largest group of soil separates, defined by the diameter from 2 mm to 0.05 mm according to CSSC. The sand fraction is subdivided into five sub-fractions (very coarse, coarse, medium, fine, and very fine).

Clayey/silty sands are widespread as naturally sedimentary soils such as marine deposits in estuaries and offshore locations. They belong to a unique class of gap-graded soils featuring a deficiency of certain range of particle sizes and behave differently from those containing pure sand aggregates.
