sedimentation is the technique (method) of separating sand and water. From H.P
Filtration
Simply filtration. In these types of separation questions, please think of the different properties of the substances you want to separate. In this case, Sand doesn't dissolve in water, so if you filter the mixture, you will get sand as the residue and water as the filtrate.

Evaporation
mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.
Panning
evaporation of the water. Water boils at a relatively low temp. sand does not, so sand would be left behind.
Filtering is the best and simplest method.By sieving small particles remain in water.
Distillation for the two soluble liquids (which seperates them by their boiling point) and magnetism for the separation of iron pins and sand.

simple distillation
- Sand is separated by filtration- Kerosene is separated by decantation (or with a special separation funnel) from water
As an isolated process milling is not a separation technique.
Evaporation
First decant the water - the sand will be left behind. Then evaporate the water and the salt will be left behind.
This sounds like a physical separation question where the student receives a beaker of sand and salt or sand and sugar and is asked to separate the two substances. The technique is to filter the mixture with water. The sand stays in the funnel, but the salt or sugar crystals dissolve in the water and are pulled through to the flask below. If you need to separate the salt or sugar from the water used for filtration, use a hotplate and evaporation dish to boil away the water.
heat it and let the water condense into a clean beaker.
