to remove impurities as volatile oxides
No, separating sand from water is a physical process as the chemical identities of the sand and water remain the same.
A simple filter would be suitable for separating sand and water. An alternative would be to evaporate the water, leaving the sand behind.
it makes the sand moist
You get a mixture of salt and sand. Nothing more happens.
In general, water and sand do not have a chemical relationship. Something might happen if the sand grains are partially composed of a mineral that is water soluble. In that case, water will dissolve water soluble material in sand. But that is a physicalactivity and not a chemical one. Water and sand do not react chemically.

Sand traps large particles - such as paper, stones and other foreign objects.

Molding or foundry sand is traditionally the second most common use (20 percent in 2003) of industrial sand. Sand is used in these applications to make molds into which molten metal is poured in metal casting
The sea sand fill in the river. rain water is flow the river. So the sea sand salt is remove some % the continuous function will be remove from full salt in sea sand

They are chemicals used to 'cure' sand into a hard molded shape onto which molten metal can be poured, and set into a shape.
Fire or furnace sand is generally coarser than the sand used in metal molding. It is used in building floors for acid open-hearth furnaces and in lining the cupolas and ladles that contain molten metal in the foundry industries.
No. The water is in the sand.
This allows the gases and steam to escape from the mold during casting. The grain size, shape and distribution of the foundry sand, the type and quantity of bonding materials, the density to which the sand is rammed, and the percentage of moisture used for tempering the sand are important factors in regulating the degree of permeability.
The plural form of foundry is foundries.
