With sulfuric acid it forms the rather insolubleCa-sulfate (gypsum), with HCl the formed Ca-chloride is very soluble, which can easily be washed/filtered out of sand.
sand is a base and gravel is a acid
Sand can be dissolved that's correct.
base
Sulphuric acid is used with malachite to separate the copper and the sand. This is because the copper dissolves into the solution where as the sand remains.

yes, sulfur can kill you if you digest it.
Sand can be dissolved that's correct.
base
A solution of sand in (dissolved) benzoic acid will not nbe possible. It is called a (heterogenous) mixture or suspension of sand in this liquid. However the separation can be carried out by filtration, centrifugation or sinking the sand down.
