Pour the liquid along a rough surface that would catch the solid particles but not the water.

There are multiple processes that can be used to separate sand and salt in this scenario. Here are a few options:

1. Filtration: Pass the mixture through a filter paper. The sand particles, being larger in size, will be retained on the filter paper while the salt will pass through as a dissolved solution.

2. Evaporation: Heat the mixture in the beaker to evaporate the water. As the water evaporates, the salt will be left behind as solid crystals while the sand remains unchanged.

3. Decantation: Allow the mixture to settle for a period of time. The sand, being denser, will settle at the bottom of the beaker. Carefully pour off the water (decanting) which will leave the sand behind in the beaker.

These are just a few of the possible methods. The choice of process will depend on the specific requirements and available equipment.
