use water as your solvent.
oil, being immiscible and less dense than water will float on top. oil can be easily removed from water by scooping it out.
sand will sink at the bottom.
salt will dissolve in water.
filter the water "solution" thereby separating the sand particles then let the water evaporate to reclaim the salt

add water to the mixture the salt will dissolve the oil will float on water since it is less dense using a separating funnel you can remove all the oil then only sand and salt dissolve in water remain you do a filtration to separate the two and collect the liquid to get back the salt again you heat the salt water until all water is evaporated the you get back your salt again

Add water.... the oil will separate from the salt and sand, use a turkey baster to remove oil.....then filter out sand from the water (coffee filter would work well)... then evaporate water which would leave the salt behind. I remember this from a science class years ago

add water to the mixture .salt will dissolve.filter the solution. mixture of sand and oil is left as residue. perform distillation on mixture of sand and oil. Thus all are separated.

Firstly add water in this mixture. We will separate the sand using Loading/ Sedimentation Decantation. Then we will use Seperating Funnel to separate oil. We will then use Filtration method to separate sand particles. Then evapourate the water to get salt

Use water.
The oil will float on top of the water and separate it from the sand.
The oil can be poured or scooped off the top of the water.
The salt will dissolve in the water. The water-plus-salt can be filtered or decanted, leaving sand.
The salt can be reclaimed by evaporating the water.

Add water, the oil will float to the top, skim it, the sand will settle to the bottom, pour off the salt water.

WELL, FIRST USING WATER TO CLEAN THE OIL OUT, THEN SAND IS A LITTLE BIGGER THAN SALT, THEREFORE U COULD USE FILTERS TO LET THE SALT PASS AND THE SAND STAY

Add water and stir
Use right filter to take out sand
Use centrifuge to separate oil and water-salt-solution
Evaporate water to obtain salt

1.salt and sand acn be seperated by evaporation so salt will evaporate.
2sand and oil can be seperated by filteration
