magnetic separation.
Yes
filteration
A "hard method of separation" is not an expression in chemistry.

Magnetic separation
a method of separation purify water
we will use some methodsto separate pumice from water we will use a magnateto separate sawdust from water we will use the method of sedimentation , to make it more clear we will use the method of filtration
Filtration is the most simple method.
filter
evaporation is a kind of separation method it is used for separating a dissolved solid (solute) from a liquid
magnetic force method
it is it
This is the separation with a separation funnel.
Add water, stir til sugar dissolves, fiter repeatedly until the water is clean, slow evap to retrieve the sugar. Add the dust and sand from the filter (most will have separated pretty well, sand on bottom etc) into a cup/beaker/bucket etc and fill with water, put it in a deep tray and add water very slowly to the bucket until the sawdust has all spilt over the edge. Your sand will be in the bucket and sawdust will have overflowed into the tray.
